GAS232 Dichloroethane-1,2 Standard Gastec Detector Tubes
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.
The Gastec detector tube system is comprised of a handheld Gastec air sampling pump and Gastec detector tubes.
