The cGas Detector Carbon Dioxide Transmitter is a low maintenance gas monitoring device designed for use in 
non-explosion rated, commercial applications that require continuous monitoring of CO2.
It offers one 4-20 mA analog output or a user selectable in the field digital output with your choice of BACnet® 
or Modbus® for communicating with a Building Automation System or ventilation controller. Ideal for use for
applications where compressed CO2 is used and stored, climate control in commercial buildings and other processes
requiring the continuous monitoring of CO2.
Powered by 24 VDC or ground referenced AC, the CO2 cGas Detector has an LCD display, temperature compensation, 
thermal resetting fuse 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 CO2 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.
