Co2 Transmitters


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.
