GASTEC o-Cresol Detector Tube 61 Instructions

GASTEC o-Cresol Detector Tube 61

FOR SAFE OPERATION

Carefully read this manual and the instruction manual of your Gastec Gas Sampling Pump.

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.

CAUTION: If you do not observe the ‘following precautions, you may suffer injuries or damage to the product.

1. When breaking the tube ends, keep away from eyes.
2. Do not touch the broken glass tubes, pieces and reagent with bare hand(s).
3. The sampling time represents the time necessary to draw the air sample through the tube. The tube must be positioned in the desired sampling area for the entire sampling time or until the flow finish indicator indicates the end of the sample.

NOTES : For maintaining the performance and reliability of the test results, observe the following.

1. Use Gastec Gas Sampling Pump together with Gastec Detector Tubes only for the purposes specified in the instruction manual of the detector tube.
2. Use this tube within the temperature range of 10 – 40°C (50 – 104°F).
3. Use this tube within the relative humidity range of 0 90%.
4. This tube may be interfered with by the coexisting gases. Please refer to the table “INTERFERENCES” below.
5. Shelf life and storage condition of the tube are marked on the label of the box of tube.

APPLICATION OF THE TUBE

Use this tube for the detection of o-Cresol in air or industrial areas and environmental atmospheric condition.

SPECIFICATION

(Because of Gastec’s commitment to continued improvement, specifications are subject to change without notice.)

Coefficient of Variation: 15% (for 1 to 5 ppm), 10% (for 5 to 25 ppm)

• Shelf Life: Please refer to the validity date printed on the box of tube.
• Store the tubes in the refrigerator to keep at 10°C (50°F) or below.

CORRECTION FOR TEMPERATURE, HUMIDITY, AND PRESSURE:
Temperature: Correct for temperature by the table below:

Humidity: No correction is required.
Pressure: To correct for pressure, multiply the tube reading by

MEASUREMENT PROCEDURE

1. For leak checking of the pump insert a fresh sealed detector tube into pump. Follow instructions provided with the pump operating manual.
2. Break tips off a fresh detector tube in the tube tip breaker of the pump.
3. Insert the tube into the pump inlet with arrow ( G► ) on the tube pointing toward pump.
4. Make certain the pump handle is all the way in. Align guide mark on the pump body with the guide mark on the handle.
5. Pull handle all the way out until it locks at one pump stroke (100 ml). Wait 1.5 minutes and confirm the completion of sampling. Repeat the above sampling procedure one more time.
6. For smaller measurements, less than 1 ppm, repeat the above sampling procedure two more times until the stain reaches to the first calibration mark. For measurements higher than 25 ppm, prepare a fresh tube and perform one pump stroke.
7. Read concentration level at the interface where the stained reagent meets the unstained reagent.
8. If temperature correction is necessary, obtain the true concentration by using the temperature correction factor. Afterwards multiply the correction factor of pump strokes if necessary.
9. If pressure correction is necessary, use the pressure correction formula.

INTERFERENCES

This table of interference gases primarily expresses the interference of each coexisting gas in the gas concentration range, that is equivalent to the gas concentration. Therefore, the test result may be given positive result by the other substances not listed in the table. For more information is needed, please contact us or Gastec representatives.

APPLICATION FOR OTHER SUBSTANCES :
Tube 5·1 can also be used for other substances as below:

CORRECTION FACTOR:
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. Therefore, please make use of the correction factor/chart measuring ranges as a reference. For more precise factor please contact your Gastec representatives.

DANGEROUS AND HAZARDOUS PROPERTIES:
Threshold Limit Value-Time Weighted Average by ACGIH (2020): 20 mg/m3(1Fv1

INSTRUCTIONS ON DISPOSAL:
The reagent of the tube does not use toxic substances. When disposing the tube regardless of whether it hasbeen used or not, follow the rules and regulations of your local government.

WARRANTY

If you have any questions regarding gas detection and quality of the tubes, please feel free to contact your Gastec representatives.
