EE850 CO2 and Temperature Sensor for Duct Mounting The EE850 combines CO2 and temperature (T) measurement in an innovative enclosure. It is ideal for demand controlled ventilation and building automation. With a CO2 measuring range of up to 10 000 ppm and a T working range of -20...+60 °C (-4...+140 °F), the EE850 can be employed also in demanding climate and process control applications. Long-Term Stability The EE850 incorporates the E+E dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability. High Measurement...

Service interface Knockout for ½" conduit-fitting (US) External mounting holes ▪ Easy and fast mounting with closed cover ▪ Electronics protected against construction site pollution Bayonet screws ▪ Open / close with a ¼ rotation Electronics ▪ CO2 auto-calibration ▪ Temperature compensation ▪ Excellent resistance to pollution ▪ Optimum protection against mechanical damage during installation Test report According to DIN EN 10204-2.2

Features Accredited Traceable Calibration Certificate Internationally recognised certificates for the calibration of measuring instruments from accredited laboratories document the traceability of the measurements to the International System of Units (SI). The E+E Elektronik calibration laboratory offers two levels of traceable calibrations. ▪ As a Designated Institute (DI) of the Republic of Austria, the E+E calibration laboratory maintains Austria’s national measurement standards for humidity, dew point temperature, air velocity and CO2. This authorises the E+E calibration laboratory to issue...
