Air quality CO2 transmitter

The CO2 concentration is measured through non-dispersive infrared (NDIR) waveguide technology with ABC automatic background calibration algorithm. The applied measuring technology guarantees excellent reliability and long term stability. The microprocessor samples the CO2 once per second. It calculates an averaging signal over a preset number of seconds and generates the output signal.

Standard signal ranges are 0-10 VDC, 2-10 VDC, 4-20 mA and 0-20 mA. Other ranges can be defined by using the external display and programming module OPA-S / OPU-S.

Applications

Demand based ventilation for homes and offices based on measurement of the CO2 concentration
Preset standard measuring range 0...2000 ppm, max possible range 0...5000 ppm
Recording of minimum and maximum limits for critical environments
Direct ventilation control of extraction fan
Air measurement
Zone control
