Product Description


GAS77 tert-Butyl Mercaptan & Dimethyl Sulphide Standard Gastec Detector Tubes

Gas detector tubes are glass tubes that are filled with a chemical reagent that absorbs and reacts with the target gas or vapour being measured. Gastec tubes do not contain hazardous substances

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

Specific shelf life requirements must be identified at the point of order placement (use the comment box in the checkout process). The expiry date is printed clearly on the front of the detector tube packet.
