MEASUREMENT PROCEDURE:
1. For checking the leakage of the pump, insert a freshly sealed detector tube into pump.
Follow the instructions provided with the pump operating manual.
2. Break the tips off a fresh primary tube and analyser tube using the tube tip breaker of the
pump.
3. Connect

marked ends with rubber tubing after breaking each end.
4. Insert the analyser tube securely into pump inlet with arrow ( ) on the tube pointing
toward the pump.
5. Make certain the pump handle is all the way in. Align guide marks on pump body with the
guide marks on the handle.
6. Pull the handle all the way out until it locks at one pump stroke (100 mL). Wait two minutes
and confirm the completion of the sampling. Repeat three more times.
7. Read concentration level at the interface where the stained reagent meets the unstained
reagent.
8. If necessary, multiply the reading by the correction factors of the pump strokes and
atmospheric pressure respectively.
INTERFERENCES:
Substance Concentration Interference Interference gas only
Chlorine 6ppm + Pale purple
Bromine 4.5ppm No No
Iodine 4.5ppm No No
1,1,1-trichloroethane + Pale purple
Trichlorethylene + Pale purple
The table of this 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 show positive result due to other substances not listed in the table. If more information is
needed, please contact us or our distributors in your territory.
DANGEROUS AND HAZARDOUS PROPERTIES:
Threshold Limit Value-Time Weighted Average by ACGIH (2009): 10 ppm
INSTRUCTIONS ON DISPOSAL:
Reagent of the tube does not use toxic substance. When disposing the tube regardless of
whether it has been used or not, follow the rules and regulations of the local government.
WARRANTY:
If you have any questions regarding gas detection and quality of the tubes, please
