Duct CO2 sensors
Duct HVAC transmitters to measure CO2, temperature and relative humidity in air ducts. The black mounting flange makes it easier to install on circular ducts. Settings can be adjusted via Modbus RTU. The sensors transfer the measured values to the corresponding analogue output or a Modbus RTU register. The CO2 duct sensors use the NDIR technology since this method is less sensitive to mechanical interferences.
