REMS 611311 Quick-Change Gas Sensor GS4-S

The REMS 611311 quick-change gas sensor GS4-S is a replacement or spare sensor head for the REMS Detect GS4 gas leak detector, giving it the ability to detect ammonia (NH3). 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 ammonia leaks, useful on industrial refrigeration and certain cooling systems where ammonia is used as the refrigerant.

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.
