Duct Carbon Dioxide Sensors


This PGS-CO2 series uses a non-dispersive infrared sensor to measure CO2 concentrations using an electronic microprocessor and a unique self-calibration algorithm to improve long-term stability and accuracy.

The sensor can be used to ensure adequate ventilation, maximizing energy savings through ventilation at the ideal level, making it ideal for all types of ventilation in commercial buildings, industrial plants, laboratories and public spaces such as schools.
