These products are used to measure air quality in HVAC/R environments. They measure on demand room ventilation, duct air flow, and are used to transmit carbon dioxide readings.
Combines accurate CO2 measurements with a passive temperature output. The Non-Dispersive Infrared (NDIR) sensor continuously updates the calibration through a proprietary logic feature which limits the amount of error due to drift. The CDW series is ideal for building automation systems to help control the fresh air intake in a room.
