EE850 Duct-Mounted CO2, Temperature & Humidity Transmitter | E+E
EE850 DUCT-MOUNTED CO2, TEMPERATURE & HUMIDITY TRANSMITTER  | E+E
The E850 by E+E Elektronik is a high-accuracy, 3-in-1 duct-mounted transmitter for carbon dioxide (CO₂), temperature, and relative humidity (RH). An innovative duct-mounted transmitter combining CO₂, temperature, and humidity sensors for building automation and HVAC control. The multi-point CO₂ and temperature factory adjustment leads to an excellent CO₂ measurement accuracy over the entire temperature working range. An optional adapter facilitates easy configuration and adjustment via the EE850 service interface.

TYPICAL APPLICATIONS

  • Building automation
  • Demand controlled ventilation
  • Process control

EE850 DUCT-MOUNTED CO2, TEMPERATURE & HUMIDITY TRANSMITTER  | E+E

The EE850 uses advanced dual-wavelength NDIR technology to monitor CO₂ levels up to 10,000 ppm, providing long-term stability by compensating for aging effects and pollution. Its functional enclosure and divided probe design allow for easy installation while ensuring high measurement accuracy across its entire operating range (-20 to 60 °C).

PRODUCT USES:

  • Demand-controlled ventilation (DCV).
  • Building automation and energy management.
  • Demanding climate and process control.
  • Air quality monitoring in offices, schools, and hospitals.
