The E+E EE80 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.

Applications for the EE80 include:

• Building management for residential and office areas
  
• Ventilation control
