REMS 611313 Quick-Change Gas Sensor GS4-H

The REMS 611313 quick-change gas sensor GS4-H is a replacement or spare sensor head for the REMS Detect GS4 gas leak detector, built specially for detecting hydrogen. In plain terms: instead of buying a whole new detector, you simply plug in this colour-coded sensor head and your existing Detect GS4 is ready to find hydrogen leaks specifically, without false alarms from other inflammable gases that might be present nearby.

It fits without tools, pushing straight onto the detector body or the 200mm flexible extension, so swapping sensors between jobs takes seconds. The colour coding makes it easy to identify at a glance, even when you're carrying a few different sensor heads in your kit.
