GAS DETECTION SYSTEM Detector Tubes List 18 th edition
PREPARATION Inspecting the pump model GV-100 before measurement (air leak check) (1) Confirm that the inlet clamping nut is firmly tightened. (2) After confirming that the pump handle is fully in (therefore, the guide line on the pump shaft is not seen),insert a fresh unbroken detector tube into the rubber inlet of the pump. (3) Align the guide mark (red line) on the back plate and the guide mark (▲100) on the handle. (4) Pull out the handle fully along the red guide line on the pump shaft to the lock position, and wait 1 minute. (5) Unlock the handle by turning it more than 1/4 turns and guide it back gradually. (6) Confirm the handle returns to the initial position and the guide line on the pump shaft is not seen. NOTE When the handle is unlocked, be sure to guide it back gradually by applying a little resistance. Otherwise, the handle will spring back due to the vacuum in the pump cylinder and possibly damage internal parts.

OPERATION Simple and accurate measurements with the Gastec standard detector tube system a) Insert the detector tube end straight into the tube tip breaker of the Pump. b) Rotate the detector tube so that the diamond cutter of the tube tip breaker scratches the surface of the tube end. c) Hold the detector tube firmly near the tube tip breaker and bend the tube toward you to break the tube tip. ▲ d) Confirm the pump handle is fully pushed in (therefore, the guide line on the pump shaft is not seen). Then insert the detector tube into the rubber inlet of the Pump with the arrow ( ) on the tube pointing toward the pump. e) Align the guide mark (red line) on the back plate and the guide mark (▲100 or ▲50 depending on the detector tube) on the hundle. f) Direct the tube end to the point of measurement and pull out the handle fully (for 100mL sampling) or halfway (for 50mL sampling) along the guide line to the lock position. 6 5 6 6 6 5 6 4 5 5 5 4 4 4 4 g) Wait until the sampling time has elapsed. The completion of the sampling of 100mL or 50mL can be confirmed by the flow finish indicator on the handle. Hints for detector tube reading (a) When the end of the colour change layer is flat: Read the value at the end of the layer. In this example, the reading should be 5%. (b) When the end of the colour change layer is slanted: Read the value in the middle of the slant. In this exaggerated example, the reading should be 5%. (c) When the demarcation of the colour change layer is pale: Read the value in the middle between the dark layer end and the pale layer end. In this exaggerated example, the reading should be 5%. △ NOTE Read instructions for your Gastec detector tube and model GV100S carefully. 2

Mesh: Correction Factor/Chart ■Measurement procedure ① Write down the starting time of measurement on an adhesive label included inside each box of Dosi-tubes, and place the label onto the tube. ② Insert the G marked end of the Dosi-tube into the No.710 Tube Holder, and break the tube end at the breaking line (A). Remove the broken end from the Tube holder. ④ Attach the Tube Holder with the Dositube to the shirt collar for personal sampling, or put it on an appropriate measurement polnt in the workplace for area monitoring. ⑤ When the measurement is finished, write down the finishing time on the label, and determine the actual sampling time : = (finishing time) - (starting time) ⑥ Obtain the average concentration (TWA value) by the following formula. Dosi-tube reading (ppm･hr) TWA value (ppm) = Actual sampllng time (hr) ③ Insert the Dosi-tube fully into the Tube holder. 26

The Polytec tubes are unique detector tubes, each having 1 to 7 reaction layers to determine multiple unknown substances in the sample simultaneously. When you pull the handle of the Pump and wait for a predetermined sampling time, the colour (s) of the Polytec tube’s layer (s) change uniquely according to the contents of the sample. Four types of Polytec tubes are available: Polytec I (No.107), Polytec II (No.25), Polytec III (No.26), and Polytec IV (No.27).

Easy to use, the Airtec tube is an accurate and precise method for detecting CO, CO2, Water vapour, Nitrogen oxides and Oil mist. Using Airtec tube direct reading vapour tubes, simply connect the pressure reducer to your high pressure air source, compressor, cylinder, or air line and adjust the flowmetre to the required setting. Opereators often produce or are performed in the presence of harmful airborne contaminants. When self-contained breathing apparatus or other devices are used for respiratory protection, the quality of the breathing air requires special attention. Contaminants entering the compressor or contaminants generated by the compressor can be harmful to the worker and the respiratory equipment. Airtec tube is a convenient economical system for testing the quality of your compressed breathing air. You do not have to learn how to operate and calibrate sophisticated instrumentation. With Aritec Tube, the measurement is quick and simple and dose not require user calibration. Just snap off both “break away” ends of the tube, insert the tube into the tube holder with the directional arrow pointing down, and adjust the flowmetre to the specified flow rate. After the required time, note where the colour stain stops and take the measurement from the direct reading tube. ■ Measurement procedure: (a case of contaminant test in cylinder) 1. Install a pressure reducer with gauge and flowmetre to a cylinder, compressor or air line and adjust the flowmetre the required setting. ① 3. Attach the rubber tube holder to the flowmetre outlet. Make certain the tube arrow on the tube pointing in a down direction. ③ 5. Time the sampling time with a stopwatch. ⑤ 29 2. Break tips off a fresh detector tube in the tube tip breaker and insert a tube into a tube holder. ② 4. Turn on the cylinder or compressor and confirm the flow metre according to each Airtec tube specifications. ④ 6. As soon as sampling time has elapsed turn off the cylinder or compressor, and remove the tube from the tube holder and then read colour change layer immediately. ⑥

Quantity of tubes per box: 10 tubes each Tube No. & Name: Gastec Detector Tube to be used. ■ Storage and disposal of Gastec detector tubes As detector tubes contain sensitive reagents that are ready to react, and some reagents might be corrosive, care should be taken for their storage and disposal. Measuring Range: Measuring ranges can be obtained by multiple or half pump strokes taken. TLV: Threshold Limit Value (TLV) for 2011 adopted by American Conference of Governmental Industrial Hygienists (ACGIH). Storage of detector tubes To keep the high quality of Gastec detector tubes, it is necessary to store them in a cool (0 to 10℃ (32 to 50°F), dark place (never expose them to the direct sunlight). Never store tubes above normal room temperature. Keep them in a safe place and out of reach of children. ● TLV-TWA: Threshold Limit Value-Time Weighted Average -the timeweighted average concentration for a normal 8-hour workday and a 40-hour workweek, to which nearly all workers may be repeatedly exposed, day after day, without adverse effect. TLV-C: The concentration that should not be exceeded during any part of the working exposure. Disposal of detector tubes Used or date-expired detector tubes should be disposed properly in accordance with your local regulations. For further information, consult your Gastec representative. ● ■ Units of concentrations % (Per cent) Ratio of the volume of a substance to the volume of its medium expressed in percentage: Volume of substance = × 100 Volume of medium Relations between concentration units ppm = % × 10,000 ● % ppb = % × 10,000,000 % ppm (parts per million) Ratio of the volume of a substance to the volume of its medium expressed in parts per million: Volume of substance = × 106 Volume of medium ppb (parts per billion) Ratio of the volume of a substance to the volume of its medium expressed in parts per billion: Volume of substance = × 109 Volume of medium = ppm × 0.0001 = ppb × 0.0000001 mg/m3 M 273 P = ppm×──×────×─── 22.4 (273+t) 1013 22.4 (273+t) 1013 ppm = mg/m3×──×────×─── M 273 P 22.4 (273+t) 1 % = mg/L×──×────×── M 273 10 M 273 mg/L = %×──×────×10 22.4 (273+t) Where : mg/m3 (milligrams per cubic metre) Ratio of the weight of a substance expressed in mg to the volume of its medium of 1 m3 (1,000L). This unit is mainly used for concentrations of particulate substances, but can also be applied to gases and vapours. mg/L (milligrams per litre) Ratio of the weight of a substance expressed in mg to the volume of its medium of 1L. This unit is mainly used for concentrations of particulate sub-stances. but can also be applied to gases and vapours. LB/MMCF (pounds per millon cubic feet) Ratio of the weight of a substance expressed in LB to the volume of its medium of 1,000,000 cubic feet. 1mg/L = 1000mg/m3 = 1358ppm = 62.3LB/MMCF (25° C,1013hPa) M: Molecular weight C F) 22.4 (L) : Volume of 1 mol at 0° (32° under l atmospheric pressure 273 (° : ° represents an absolute K) K temperature. 0° 273° t° C≒ K, C=(273 + t)° K 1013 (hPa) : 1 atmospheric pressure in hectopascal P : Atmospheric pressure at the time of measurement in hectopascal Note: T Tubes need a temperature correction factor or table for the true concentration. H Tubes need a humidity correction factor or table for the true concentration. + Five tests (tubes) per box. Twin tubes to be combined with primary and analyzer tubes. ++ Nine tests (tubes) per box. M Tube 121SP Benzene tube in the mixture of other Hydrocarbons. + ⃝ Five tests (tubes) and long size glass detector tube for tube 31B only. Shelf Life (year): Actual shelf life (the term of validity) is printed on the tube box in final inspection process. Refrigerated Storage: ＊Tubes to be stored at 10° (50° or below. C F) No. of Pump Strokes: Number in circle means standard pump strokes. One ① stroke of the sampling pump draws a 100ml air 1/2 sample. One half ⃝pump strokes draw a 50ml air sample. Correction factor/chart: Mesh means a correction factor or chart for the true concentration which is enclosed with each box of detector tubes. Detector tubes are primarily designed to measure specific gases. But it is also possible to measure other substances of similar chemical properties with the aid of a correction factor or chart. A correction factor is a figure which is multiplied by the concentration interpreted from the colour starting on the detector tube. The correction may also be presented as a chart on tube if the correction relationship is nonlinear. Therefore, please make use of the correction factor/chart measuring ranges as a reference. Moreover, this factor may vary slightly between production batches. For a more precise factor please contact your Gastec distributor. Tube 72P Tube No.72P works directly off regulated residential LP gas line pressure. Warning 1. Use only Gastec detector tubes in a Gastec Pump. 2. Do not interchange or use non-Gastec parts or components in Gastec's detector tube and pump system. 3. The use of non-Gastec parts or components in Gastec's detector tube and pump system or use of a non-Gastec detector tube with a Gastec pump or use of a Gastec detector tube with a non-Gastec pump may result in property damage, serious bodily injury, and death; voids all warranties; and voids all performance and data accuracy guaranties. 36

    PREPARATION Inspecting the pumpmodel GV-100 before measurement (air leak check) (1) Confirm that the inlet clamping nut is firmly tightened. (2) After confirming that the pump handle is fully in (therefore, the guide line on the pump shaft is not seen),insert a fresh unbroken detector tube into the rubber inlet of the pump. (3) Align the guide mark (red line) on the back plate and the guide mark (▲100) on the handle. (4) Pull out the handle fully along the red guide line on the pump shaft to the lock position, and wait 1 minute. (5) Unlock the handle by turning it more than 1/4 turns and guide it back gradually. (6) Confirm the handle returns to the initial position and the guide line on the pump shaft is not seen. NOTE When the handle is unlocked, be sure to guide it back gradually by applying a little resistance. Otherwise, the handle will spring back due to the vacuum in the pump cylinder and possibly damage internal parts.

    OPERATION Simple and accuratemeasurements with the Gastec standard detector tube system a) Insert the detector tube end straight into the tube tip breaker of the Pump. b) Rotate the detector tube so that the diamond cutter of the tube tip breaker scratches the surface of the tube end. c) Hold the detector tube firmly near the tube tip breaker and bend the tube toward you to break the tube tip. ▲ d) Confirm the pump handle is fully pushed in (therefore, the guide line on the pump shaft is not seen). Then insert the detector tube into the rubber inlet of the Pump with the arrow ( ) on the tube pointing toward the pump. e) Align the guide mark (red line) on the back plate and the guide mark (▲100 or ▲50 depending on the detector tube) on the hundle. f) Direct the tube end to the point of measurement and pull out the handle fully (for 100mL sampling) or halfway (for 50mL sampling) along the guide line to the lock position. 6 5 6 6 6 5 6 4 5 5 5 4 4 4 4 g) Wait until the sampling time has elapsed. The completion of the sampling of 100mL or 50mL can be confirmed by the flow finish indicator on the handle. Hints for detector tube reading (a) When the end of the colour change layer is flat: Read the value at the end of the layer. In this example, the reading should be 5%. (b) When the end of the colour change layer is slanted: Read the value in the middle of the slant. In this exaggerated example, the reading should be 5%. (c) When the demarcation of the colour change layer is pale: Read the value in the middle between the dark layer end and the pale layer end. In this exaggerated example, the reading should be 5%. △ NOTE Read instructions for your Gastec detector tube and model GV100S carefully. 2

Easy to use, the Airtec tube is an accurate and precise method for detecting CO, CO2, Water vapour, Nitrogen oxides and Oil mist. Using Airtec tube direct reading vapour tubes, simply connect the pressure reducer to your high pressure air source, compressor, cylinder, or air line and adjust the flowmetre to the required setting. Opereators often produce or are performed in the presence of harmful airborne contaminants. When self-contained breathing apparatus or other devices are used for respiratory protection, the quality of the breathing air requires special attention. Contaminants entering the compressor or contaminants generated by the compressor can be harmful to the worker and the respiratory equipment. Airtec tube is a convenient economical system for testing the quality of your compressed breathing air. You do not have to learn how to operate and calibrate sophisticated instrumentation. With Aritec Tube, the measurement is quick and simple and dose not require user calibration. Just snap off both “break away” ends of the tube, insert the tube into the tube holder with the directional arrow pointing down, and adjust the flowmetre to the specified flow rate. After the required time, note where the colour stain stops and take the measurement from the direct reading tube. ■ Measurement procedure: (a case of contaminant test in cylinder) 1. Install a pressure reducer with gauge and flowmetre to a cylinder, compressor or air line and adjust the flowmetre the required setting. ① 3. Attach the rubber tube holder to the flowmetre outlet. Make certain the tube arrow on the tube pointing in a down direction. ③ 5. Time the sampling time with a stopwatch. ⑤ 29 2. Break tips off a fresh detector tube in the tube tip breaker and insert a tube into a tube holder. ② 4. Turn on the cylinder or compressor and confirm the flow metre according to each Airtec tube specifications. ④ 6. As soon as sampling time has elapsed turn off the cylinder or compressor, and remove the tube from the tube holder and then read colour change layer immediately. ⑥

    Quantity of tubesper box: 10 tubes each Tube No. & Name: Gastec Detector Tube to be used. ■ Storage and disposal of Gastec detector tubes As detector tubes contain sensitive reagents that are ready to react, and some reagents might be corrosive, care should be taken for their storage and disposal. Measuring Range: Measuring ranges can be obtained by multiple or half pump strokes taken. TLV: Threshold Limit Value (TLV) for 2011 adopted by American Conference of Governmental Industrial Hygienists (ACGIH). Storage of detector tubes To keep the high quality of Gastec detector tubes, it is necessary to store them in a cool (0 to 10℃ (32 to 50°F), dark place (never expose them to the direct sunlight). Never store tubes above normal room temperature. Keep them in a safe place and out of reach of children. ● TLV-TWA: Threshold Limit Value-Time Weighted Average -the timeweighted average concentration for a normal 8-hour workday and a 40-hour workweek, to which nearly all workers may be repeatedly exposed, day after day, without adverse effect. TLV-C: The concentration that should not be exceeded during any part of the working exposure. Disposal of detector tubes Used or date-expired detector tubes should be disposed properly in accordance with your local regulations. For further information, consult your Gastec representative. ● ■ Units of concentrations % (Per cent) Ratio of the volume of a substance to the volume of its medium expressed in percentage: Volume of substance = × 100 Volume of medium Relations between concentration units ppm = % × 10,000 ● % ppb = % × 10,000,000 % ppm (parts per million) Ratio of the volume of a substance to the volume of its medium expressed in parts per million: Volume of substance = × 106 Volume of medium ppb (parts per billion) Ratio of the volume of a substance to the volume of its medium expressed in parts per billion: Volume of substance = × 109 Volume of medium = ppm × 0.0001 = ppb × 0.0000001 mg/m3 M 273 P = ppm×──×────×─── 22.4 (273+t) 1013 22.4 (273+t) 1013 ppm = mg/m3×──×────×─── M 273 P 22.4 (273+t) 1 % = mg/L×──×────×── M 273 10 M 273 mg/L = %×──×────×10 22.4 (273+t) Where : mg/m3 (milligrams per cubic metre) Ratio of the weight of a substance expressed in mg to the volume of its medium of 1 m3 (1,000L). This unit is mainly used for concentrations of particulate substances, but can also be applied to gases and vapours. mg/L (milligrams per litre) Ratio of the weight of a substance expressed in mg to the volume of its medium of 1L. This unit is mainly used for concentrations of particulate sub-stances. but can also be applied to gases and vapours. LB/MMCF (pounds per millon cubic feet) Ratio of the weight of a substance expressed in LB to the volume of its medium of 1,000,000 cubic feet. 1mg/L = 1000mg/m3 = 1358ppm = 62.3LB/MMCF (25° C,1013hPa) M: Molecular weight C F) 22.4 (L) : Volume of 1 mol at 0° (32° under l atmospheric pressure 273 (° : ° represents an absolute K) K temperature. 0° 273° t° C≒ K, C=(273 + t)° K 1013 (hPa) : 1 atmospheric pressure in hectopascal P : Atmospheric pressure at the time of measurement in hectopascal Note: T Tubes need a temperature correction factor or table for the true concentration. H Tubes need a humidity correction factor or table for the true concentration. + Five tests (tubes) per box. Twin tubes to be combined with primary and analyzer tubes. ++ Nine tests (tubes) per box. M Tube 121SP Benzene tube in the mixture of other Hydrocarbons. + ⃝ Five tests (tubes) and long size glass detector tube for tube 31B only. Shelf Life (year): Actual shelf life (the term of validity) is printed on the tube box in final inspection process. Refrigerated Storage: ＊Tubes to be stored at 10° (50° or below. C F) No. of Pump Strokes: Number in circle means standard pump strokes. One ① stroke of the sampling pump draws a 100ml air 1/2 sample. One half ⃝pump strokes draw a 50ml air sample. Correction factor/chart: Mesh means a correction factor or chart for the true concentration which is enclosed with each box of detector tubes. Detector tubes are primarily designed to measure specific gases. But it is also possible to measure other substances of similar chemical properties with the aid of a correction factor or chart. A correction factor is a figure which is multiplied by the concentration interpreted from the colour starting on the detector tube. The correction may also be presented as a chart on tube if the correction relationship is nonlinear. Therefore, please make use of the correction factor/chart measuring ranges as a reference. Moreover, this factor may vary slightly between production batches. For a more precise factor please contact your Gastec distributor. Tube 72P Tube No.72P works directly off regulated residential LP gas line pressure. Warning 1. Use only Gastec detector tubes in a Gastec Pump. 2. Do not interchange or use non-Gastec parts or components in Gastec's detector tube and pump system. 3. The use of non-Gastec parts or components in Gastec's detector tube and pump system or use of a non-Gastec detector tube with a Gastec pump or use of a Gastec detector tube with a non-Gastec pump may result in property damage, serious bodily injury, and death; voids all warranties; and voids all performance and data accuracy guaranties. 36
