★ READ THIS INSTRUCTION MANUAL AND THE INSTRUCTIONS OF THE ASPIRATING PUMP PRIOR TO
USING THIS PRODUCT.
★ DO NOT DISCARD CAREFULLY THIS INSTRUCTION MANUAL UNTIL ALL OF THE TUBES IN THIS BOX
ARE USED UP.

Aspirating Pump
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.
4. IF THE CONCENTRATION IS OVER THE FULL SCALE, THE HIGH CONCENTRATION
OF HYDROGEN SULPHIDE REMAINS IN THE ASPIRATING PUMP. BE CAREFUL NOT
TO BREATHE THE REMAINING GAS. AFTER MEASUREMENT, THE REMAINING GAS
IS PUSHED OUT FROM THE BOTTOM CASE OF THE PUMP (FROM A IN FIG.1)
WHEN THE HANDLE IS PUSHED BACK AND PULLED. IN CASE OF THE ABOVE, PUSH BACK
AND PULL THE HANDLE WITHOUT CONNECTING THE TUBE AT THE LOCAL EXHAUST
VENTILATION DEVICE. REPEAT THIS OPERATION AT LEAST FIVE TIMES IN ORDER TO
REMOVE THE REMAINING GAS.
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.2. (Arrow mark shall point to the pump.)
③ Align the guide marks on the shaft and stopper of the aspirating pump.
④ Pull the pump handle at a full stroke until it locks and wait for 1 minute 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.
⑥ When the concentration is over the scale range, a 1/2 pump stroke can be used to determine concentrations of 0.2 - 6.0
ppm.
1)Remove the detector tube from the pump.
