Description
The CERMC Carbon Dioxide Sensor uses a highly accurate and reliable non-dispersive infrared (NDIR) sensor in an attractive, wall mount enclosure to monitor return air CO2 levels for indoor applications.
The compact dual wavelength CO2 sensor achieves excellent performance characteristics, including high accuracy and low power consumption to ensure stable long term operation. The CE features both 4-20 mA and voltage outputs (0-5 / 0-10 Vdc) for simple integration into any building automation system for the improvement of energy savings and to assure good indoor air quality.
Features
- Dual wavelength NDIR
- Selectable outputs
