★ 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 THE TUBES IN THIS BOX

1. THE DETECTOR TUBE AND PRETREAT TUBE CONTAIN 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 WILL 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 REFRIGERATED PLACE ( 0-10 ℃/32-50°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 pretreat tube (Ⅰ) and detector tube (Ⅱ), and connect each end of the pretreat
tube and detector tube with connecting tube connector as shown in Fig.1.
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 handle and stopper of the aspirating pump.
④ Pull the pump handle at a full stroke until it locks and wait for 2 minutes or until the completion of sampling is
confirmed with the flow indicator of the pump. ( See descriptions about the flow indicator in the instructions
manual of the pump.)
⑤ Turn the pump handle right or left by 1/4 ( 90
from the pump and repeat the step ③ to ④ three times more.
⑥ On completion of sampling, read the scale at the maximum point of the stained layer.
⑦ When the concentrations are over the scale range, 1 pump stroke can be used to determine concentrations of
0.7 to 14.0. After the above ① to ④ and completion of sampling, read the scale at the maximum point of
the stained layer and correct the reading value by using correction table for 1 pump stroke.
(REFER TO ITEM 3. CORRECTION FOR AMBIENT CONDITIONS.)
SPECIAL NOTE: Ⅰ. The scale is calibrated at 20 ℃ (68°F), 50 %R.H. and 1013hPa. Readings obtained in
3. CORRECTION FOR AMBIENT CONDITIONS:
(In case of 4 pump strokes)
① Temperature; The scale is calibrated based on the temperature of 20 ℃ (68°F). Readings obtained in
other temperature circumstances should be corrected with the following temperature correction table.
Temperature(℃)
Procedure of temperature correction:
Actual reading can be obtained by multiplying the reading of tubes by coefficient for temperature
correction shown in the above. Therefore,
Actual Ethylene oxide concentration ( ppm) =
Procedure to get coefficient for temperature correction from the table:
For example, in case of temperature of 23

(*)Graduations on the detector tube are based on 4 pump strokes.
: 2 minutes
: Yellow(**) → Pale pink
(**)Occasionally, the original colour of the unused tubes is reddish.
But the accuracy of the readings is not affected.
: 0 - 40 ℃ (32-104°F)(Temperature correction is necessary)
: 10 - 90 %RH (No correction is necessary)
: Model AP-20, AP-20S, 400B, AP-1, AP-1S, or 400A
other circumstances should be corrected.
(REFER TO ITEM 3. CORRECTION FOR AMBIENT CONDITIONS.)
Ⅱ. When the maximum point of the stained layer is unclear or oblique, read the scale at the
centre between the longest and shortest points.
Ⅲ. After breaking the end of detector tubes, forward to the next step as soon as possible.
If the detector tubes are left as they are after breaking the end of the detector tubes, the
original colour of reagent will be changed to pale yellow by moisture in the air. However,
even if the colour change occurs, the accuracy of the readings will not be affected.
