Senva CO2 sensors maximize energy savings by ensuring optimal ventilation. Measuring exhaled CO2 levels ensures air is conditioned only when needed. The CO2D series is duct mount sensor with NDIR sensing element and features that include a standard LCD, optional thermistor for temperature, setpoint relay, menu selectable autocalibration and provision to offset the reading +/-250ppm.


Integrated display and push-button menus for field selectable scale, calibration, and operational modes
▪ Dual 4-20mA and 0-5V/0-10V output (jumper selectable)
▪ Integrated high-reliability solid-state set-point relay is ideal for direct control applications; easy to set up thanks to LCD
▪ Non-dispersive infrared sensing element (NDIR)
▪ Field replaceable CO2 sensor
▪ 15+ year life expectancy on CO2 sensing element
▪ Selectable auto-calibration mode returns sensor to baseline values
▪ ±40ppm, ±3% of reading
