The is a compact gas monitoring system that’s ideal for continuously monitoring toxic and in hazardous areas.  The non-intrusive calibration allows sensor calibration in hazardous areas without area declassification. The only tool required is a small magnetic wand, designed to be carried on a technician’s key chain. It also allows true one-man calibration, which significantly reduces the labor and downtime commonly associated with gas detector maintenance and service.

The instrument’s fault supervision circuitry continuously monitors for failed sensor cell and communication line breaks.  Plus sensor cell operation is continuously supervised 24-7 and when used in conjunction with distributive control systems or PLC’s, provides immediate fault identification for a disconnected sensor cell.

The is housed in a Nema 7 explosion proof enclosure and is available for Carbon Monoxide, IPA, H2, H2S and other toxic gases. Capable of monitoring ppm levels of toxic gas or % LEL levels of combustible gases, the   is a perfect monitoring solution for providing worker protection in chemical plants, refineries and other areas requiring hazardous classifications.
