Sensor of Carbon dioxide, relative humidity and temperature


Using 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 also features moisture and temperature outputs and an optional backlit LCD display for all measurements. 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.
