Designed to monitor combustible gases up to the explosive limits. These sensors are used both in fixed and portable instrumentation.
Main features of these sensors are:
Response to a wide range of combustible gases
A wide range of sensor types and operating voltages
Poison & shock resistant versions available
Full technical support
The VQ500 Series is a complete range of miniature, fully certified, flameproof sensor heads containing a high quality, low power pellistor pair optimised for the detection of combustible gases or % volume gases in thermal conductivity mode. They have an outline identical to modern miniature electrochemical cells and are ideally suited for use in portable instruments.
Within the VQ500 Series there are specific sensors that are able to detect most combustible gases and vapours and ammonia at LEL levels. The thermal conductivity version will detect most gases at % volume concentrations which have thermal conductivities different from that of air.
