Fixed Gas Detection Sensor Assemblies


Gas leak detection equipment, such as fixed gas detection systems, are critical in certain environments where certain toxic leaks may become fatal to those in the area. Some gas leak detection sensors may be used to monitor refrigerants, while other fixed gas detection sensor assemblies may be dedicated to guarding against various toxic gases.
Many of the fixed gas sensor assemblies featured here are from well-respected German manufacturer GfG. We also carry an Otis unit that can be set to detect oxygen as well as various toxic substances including ammonia, carbon monoxide (CO), hydrogen, hydrogen sulfide and sulfur dioxide. This is a unique and versatile electrochemical sensor system that utilizes a non-invasive, magnetically triggered calibration process, has a long life expectancy, and is built to withstand harsh conditions and climates.
