1. THE DETECTOR TUBE CONTAINS CHEMICAL REAGENTS.
2. DO NOT TOUCH THESE REAGENTS DIRECTLY ONCE TUBES WERE BROKEN.
3. KEEP THE TUBES OUT OF THE REACH OF CHILDREN.
NOTICE
1. USE ONLY WITH PUMP MODELS AP-20, AP-20S, 400B, AP-1, AP-1S OR 400A.
OTHERWISE, CONSIDERABLE ERROR IN INDICATION MAY OCCUR.
2. BEFORE TESTING, CHECK THE ASPIRATING PUMP FOR LEAKS. ( REFER TO ITEM 8
INSPECTION OF ASPIRATING PUMP.) ANY PUMPS SHOWING SIGNS OF LEAKAGE
SHOULD BE CORRECTED BEFORE USE.
3. DO NOT USE THIS TUBE OUTSIDE THE STATED OPERATING TEMPERATURE RANGE.
4. STORE TUBES IN A COOL AND DARK PLACE ( 0-25 ℃/32-77°F), AND USE BEFORE
EXPIRATION DATE PRINTED ON THE TOP OF THE BOX.
5. PRIOR TO USE, READ ITEM 9. USER RESPONSIBILITY CAREFULLY.
6. READ THE CONCENTRATION IMMEDIATELY AFTER DRAWING THE SAMPLE.
2. SAMPLING AND MEASUREMENT:
① Break both ends of the detector tube.
CAUTION SAFETY GLASSES AND GLOVES SHOULD BE WORN TO PREVENT INJURY
FROM SPLINTERING GLASS.
② Insert the detector tube into the aspirating pump securely as shown in Fig.1. ( Arrow mark shall point to the
pump.)
③ Align the guide marks on the shaft and stopper of the aspirating pump.
④ Pull the handle at a 1/2 stroke (to 50mL line) until it locks and wait for 0.5 minutes or until the completion of
sampling is confirmed with the flow indicator of the pump. ( See descriptions about the flow indicator in the
instruction manual of the pump.)
⑤ On completion of sampling, read the scale at the maximum point of the stained layer.
1. THE TUBE WILL NOT RESPOND IN THE ABSENCE OF OXYGEN.
2. WHEN THE CONCENTRATION OF HYDROGEN IS 12 TO 16%, PRETREAT REAGENT ( BLACK
LAYER) GIVES A HEAT (ABOUT 100 ℃) BUT IS NOT DANGEROUS FOR USE IN HAZARDOUS
AREA.
3. WHEN THE CONCENTRATION OF HYDROGEN IS OVER 40%, THE READING VALUE MAY BE
INDICATED BELOW 0.8%. IN THIS CASE, THE BOTTOM OF THE DISCOLOURED LAYER
BECOMES DARK PURPLE. IN ORDER TO MAKE SURE THAT THE CONCENTRATION IS
EXTREMELY HIGH SUCH AS 40%, MEASURE THE GAS CONCENTRATION WITH
CONNECTING 2 TUBES. IF BOTH TUBES ARE DISCOLOURED TO GREEN, EXTREMELY HIGH
CONCENTRATION HYDROGEN EXIST.
