T99-CO2D Free Standing Carbon Dioxide Sensor for HVAC

The T99-CO2D Carbon Dioxide sensor is designed to be installed in HVAC applications. The CO2 sensing element uses non-dispersive infrared technology (NDIR) with the patented self-calibration system to guarantee long-term stability and up to 15 years lifetime. The one or three analogue outputs are selectable by jumpers, and a Modbus RS485 communication interface is also available.
