MEASUREMENT PROCEDURE
(Read the instruction manual of your Gastec Gas sampling pump and the
instruction manual of your Gastec Gas detector tube carefully.)
1.
Replace the rubber inlet flange clamping nut of the sampling pump by the metal clamping nut of the extension
hose. The metal clamping nut should be firmly tightened to eliminate leakage caused by poor seal between the
flange of the rubber inlet and the pump body.
2.
Insert the nipple of the extension hose securely into the pump inlet.
3.
Tighten the metal retaining nut firmly and fix the tubing on the pup head.
4.
After breaking off tube tips, place the tube into the rubber shroud of the extension hose. The tube must be
attached in the holder so that sample is drawn into the pump in the direction of the arrow (►)printed on the
tube.
5.
When use of twin tube, connect rubber tube shroud No. 358 which is sold seperately.
6.
As necessary, multiply the correction factors of temperature, humidity, pump strokes, and atomospheric
pressure. Refer to the instruction manual of your Gastec Gas Detector tube for temperature, humidity, and
pump strokes correction.
