Gas Sampling Pump Kit

GASTEC Detector Tubes indicate concentrations directly by way of a calibrated scale printed on the tubes. At GASTEC, we endeavour to achieve highest quality detector tubes for analysing airborne gases/vapours, as well as pollutants in soil and water through our advanced state-of-the-art research and development. Through our efforts we have acquired a solid reputation among our customers in virtually all sectors of industry, commerce and society. Tubes are now available for more than 500 different applications.

Benefits of Gas Sampling Pump Kit

• On-site measurements can be performed easily by anybody, anytime and anywhere, in a short time
• Easy-to-check direct reading possible due to the calibrated scale directly printed on the tube
• An extensive measuring range can be obtained by adjusting the sampling volume
• In order to assure high precision, each production lot is tested and calibrated independently, Each detector tube has its own quality control number printed on the tube
• Long shelf-life with excellent long-term stability

Gas Sampling Pump Kit Operating procedures (Simple 3-step measuring)

1

Break off both ends of the detector tube. Insert the tube into the rubber inlet.

2

Pull out the handle until it is locked. Wait until the sampling time has elapsed.

3

Wait for the required sampling time and read the measurement at the end of the coloured layer.

Airtightness Test of your sampling pump

If the sampling pump is not airtight, measurements will not yield correct results. Before starting to measure, be sure to verify that the sampling pump is really airtight.

1. First, confirm that the inlet nut is not loose.

2. Insert a detector tube (with both tips intact) into the rubber tube inlet of the sampling pump.

3. With the handle fully pushed in, align both of the guide marks (red line + triangle) on the pump (tail-end block) and the handle (▲100).

4. Pull out the handle in one thrust until it is locked, and then release the handle. Wait until the sampling time (approx. 1 minute) has elapsed.

5. Grasp the handle and turn it 90 degrees. If the pump is completely airtight, the handle should readily return to its original position; with the handle's demarcation read line fully concealed.

(Note) When you return the piston, please ease it back gradually (lightly holding on to it so it does not snap back in one thrust. (Since there is a vacuum inside the cylinder, the handle tends to return rapidly). If it snaps back too hard, the impact can damage the pump causing it to malfunction.

When the airtightness test does not provide the desired result

Primary causes of leakage in gas sampling pumps are looseness of the inlet nut, porosity of the inlet rubber, impure or insufficient sealing grease, etc. Please perform the necessary maintenance according to the procedures described in the sampling pump instructions manual. If the pump still leaks after performing the maintenance procedures according to the manual, immediately discontinue use, and contact your authorized GASTEC representative.
