E+E Elektronik CO₂, RH and T Duct Mount Transmitter for HVAC


The EE850 is a 3 in 1 duct mounted transmitter ideal for demand-controlled ventilation and building automation. It combines CO₂, humidity and temperature in an innovative and functional enclosure. 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.

  • CO2 measuring range: 0…2000ppm / 5000pp/10000ppm.
  • Humidity measuring range: 0-95%RH
  • Temperature measuring range: -20…60 °C (-4…140 °F)
  • Outputs: 0-5 / 10V, 4…20mA
  • Supply: 24V AC & 15-35VDC
  • Optional passive temperature sensor 2 wire Pt1000
