Description

The cGas Detector Analog Transmitter is a low maintenance gas monitoring device designed for use in non-explosion rated, commercial applications and is ideal for monitoring toxic, combustible and refrigerant gases.

Powered by 24 VDC or ground referenced AC, the cGas Detector has an LCD display, temperature compensation and the firmware and configuration can be upgraded in the field using the USB connection. Pre-calibrated sensors with true Plug & Play Smart Sensor technology makes replacing sensors quick and easy.

The cGas Detector comes in a standard water / dust tight, corrosion resistant ABS/ polycarbonate enclosure with a hinged, secured door. With the optional, factory installed splash guard the enclosure is IP54 rated and provides protection in water spray or wash down applications.

Note: Ethanol and Methanol are highly flammable. The cGas Detector is intended for use in non-classified areas only. Follow project specifications. If monitoring area is classified, our combustible or infrared CXT Explosion Proof products would be a suitable alternative.
