CD2RMCV Carbon Dioxide Sensor, Room, Analog Op, LCD

The CD2RMC Carbon Dioxide Transmitter series use a highly accurate and reliable Dual wavelength,Non-dispersive Infrared (NDIR) sensor in an attractive, low profile enclosure for room applications to monitor CO2, levels. A linear analog signal output of 4-20 mA, 0-5 or 0-10 Vdc is provided for connection to a building automation system. Optional features such as manual override and adjustable relay output are available.
