2. SAMPLING AND MEASUREMENT:
Fig.1
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 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
20 to 1400 ppm.
