Model:CEDTF

Description

The CEDT series uses a highly accurate and reliable non-dispersive infrared (NDIR) sensor in a duct 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. The device is also available with an optional resistive temperature sensor.

F model with Cable Gland fitting
