For monitoring: Ammonia, Carbon monoxide, Carbon dioxide, Chlorine, Ethylene, Ethylene oxide, Formaldehyde, Hydrogen, Hydrogen fluoride, Hydrogen sulphide, Nitric oxide, Nitrogen dioxide, Oxygen, Ozone, Sulfur dioxide, Ethanol, Dimethyl ether, Methanol, Methane, Propane, Hydrogen, TVOCs, Refrigerants
The cGas Detector is a digital, one or two channel gas detection transmitter that offers greater flexibility at a lower cost with customized sensor combinations and specialized options for adding only the functionality you need. It is ideal for monitoring toxic, combustible and refrigerant gases in commercial and light industrial, non-hazardous (non-explosion rated) environments.
Output is user selectable in the field with your choice of BACnet® or Modbus® for communicating with a Controller or a Building Automation System. Pre-calibrated sensors with true Plug & Play Smart Sensor technology makes replacing sensors quick and easy.
Powered by 24 VDC or ground reference AC, the digital cGas Detector it has an LCD display, temperature compensation, thermal resetting fuses and the firmware and configuration can be upgraded in the field using the USB connection. Specialized optional features include, relative humidity and temperature monitoring, low temperature operation, relay and wash-down / water spray protection.
The digital cGas Detector comes in a standard water / dust tight, corrosion resistant ABS / polycarbonate enclosure with a hinged, secured door. With the optional, factory installed standard splash guard the enclosure is IP54 rated and provides protection in water spray or wash down applications.
