Co2 Transmitters



CO2 TRANSMITTER

EE85 Series
Duct mounted C02 transmitters and switches of the EE85 series are designed for HVACapplications. The C02 sensing element usesthe NonDispersive Infrared Technology (NDIR). Apatented auto-calibration procedure compensates for drift caused by the aging of the sensing element and guarantees outstanding long term stability.
