EE80
HVAC Room CO2 Switch
EE80 room CO2 switch is based on the non-dispersive infrared
(NDIR) measurement principle. A patented auto-calibration
procedure compensates for the aging of the infrared source and
ensures outstanding long term stability.
The switch threshold and hysteresis can be set with potentiometers on the electronics board. The measured CO2 data can be
indicated on the optional LC display.
Two different enclosure designs ensure professional appearance
according to regional standards.
