Co2 Transmitter - Ndir Technology, 0-5000ppm Measurement Range | Auto-calibration, Long-term Stability, Ip65 Protection

We are manufacturing, exporting and supplying wide range of CO2 Transmitters from Ahmedabad, Gujarat, India. 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.
