CO2 Transmitter for HVAC - EE85-Image

The EE85 CO2 transmitter is ideally suited for duct mounting in the fields of building management and demand controlled ventilation.
The elegant, compact housing enables easy installation directly at the ventilation duct using a mounting flange. The EE85 C02 transmitter is also available with an integrated passive temperature measurement.
The CO2 transmitter operates according to the infrared principle (NDIR). The patented auto-calibrate function compensates for any ageing effects (even if there is no fresh air supply) and ensures excellent long-term stability.
The tried-and-tested CO2 sensors from E+E Elektronik ensure high reliability and excellent measurement accuracy. The air to be monitored is conveyed to the CO2 sensor by means of convection via the measuring head and a 12-mm pipe. Gas exchange with the CO2 sensor is carried out by diffusion via a diaphragm, i.e. the air in the CO2 sensor circulates in a closed system and there is no soiling of the optical measurement path in the CO2 sensor.

Measuring range CO2: 0...2000 / 5000 / 10000ppm Measuring range Temperature: -20...60°C
