Product Description

Details

GAS233 Chloropicrin Gastec Detector Tubes 0.045 to 22ppm

Gas detector tubes are glass tubes that are filled with chemical reagent that absorbs and reacts with the target gas or vapour being measured.

A colorimetric stain (a colour change) is created. For most tubes, the concentration is read directly from the pinpoint accurate measurement scale on each tube.

This makes this form of monitoring ideal for spot sampling as it can be more accurate then electronic gas detectors.

The Gastec detector tube system is comprised of a handheld Gastec air sampling pump and Gastec detector tubes
