Magnify

Gastec continuous sampling tubes are used with Gastec’s automatic sampling pump for continuous sampling within a workplace or a residence. Combined with Gastec’s GSP-300FT-2 automatic sampling pump, continuous sampling tubes provide easy, on site, indoor air quality analysis of many nuisance gases without the need for calibration and at a lower cost then other methods.

Gastec continuous detection tubes require an automatic sampling pump with an adjustable flow rate between 50 and 200 ml/min (different tubes require different flow rates) and powerful suction in order to maintain that rate through the high density of the detection tubes. Although any pump meeting these requirements will suffice, a deviation in flow rate will effect the accuracy of the results. Gastec manufacturers the GSP-300FT-2 automatic sampling pump specifically for use with continuous detection tubes.

What to Order

Gastec continuous detection tubes are listed below alphabetically by the gas to be detected. All Tubes come in boxes of 10 for 10 measurements and include instructions.

An electronic sampling pump is required to use continuous gas detection tubes. Different models of tubes have different requirements for flow rate. The Gastec automatic sampling pump is specifically designed for use with any of these tubes.
