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.

The multi-point CO2 and temperature factory adjustment leads to an excellent CO2 measurement accuracy over the entire temperature working range.

The EE850 can be optionally fitted with a passive temperature sensor output. An optional kit facilitates easy configuration and adjustment.
