This set, consisting of the Maxi Controller and the Dual-Beam NDIR CO2 sensor, uses a photocell that makes it particularly easy to operate.
The Separate CO2 sensor is connected to the Maxi Controller, which controls the CO2 generator or CO2 pressure reducing valve. The CO2 sensor utilises Dual Beam NDIR technology which delivers unprecedented calibration stability and accuracy. Single beam sensors need to be regularly calibrated. Dual Beam sensors are two sensors in one where the measuring sensor is periodically adjusted by the second sensor. Because the second sensor is active for only 5 minutes per month it does not age or drift.
