Product Overview

The VQ500 Series is a range of miniature, fully certified, flameproof catalytic combustible gas sensor heads. Optimized for low power consumption, these sensors utilize a pellistor pair to detect combustible gases and vapors, including ammonia, at LEL levels. Thermal conductivity versions are also available for detecting gases with thermal conductivities different from air at % volume concentrations. Designed with an outline identical to modern miniature electrochemical cells, they are ideal for integration into portable instruments. The series offers poison resistance to silicones and hydrogen sulfide, shock resistance, and is certified for hazardous environments (ATEX, IECEx, CSA, UL). Operating temperature range is from -40C to +55C.
