The PGS-CO2-x range combines CO 2, temperature or CO 2, temperature and relative humidity detection only in one box, with 2 selectable analog or Modbus outputs (depending on the selected model).
Using a non-dispersive infrared sensor for measuring CO2 concentrations and using electronically based microprocessors, the self-calibration algorithm offers long-term stability and accuracy. They are also equipped with a temperature output or relative humidity output.
The sensor can be used to ensure adequate ventilation, maximizing energy savings through the ideal level of ventilation, making it ideal for all types of ventilation in commercial buildings, industrial plants, laboratories and public spaces such as schools.
