CO2 detectors for IAQ and HVAC

ELT CD-100 (Mobile)Edaphic Scientific’s low cost yet highly accurate CO2 detectors and transmitters are ideal for HVAC installations and monitoring of indoor air quality (IAQ).

Our sensors have either voltage or 4 to 20mA outputs and are suitable for any HVAC installation and controllers such as BMS.

Edaphic Scientific also has additional CO2 sensors for HVAC including models that measure temperature, humidity, carbon monoxide and VOCs.
