DOL 17
The CO2 sensor DOL 17 is used in connection with the SKOV climate and production computers for monitoring or control of the climate based on the CO2 content in the housing air. The auto-calibration procedure of the CO2 sensor compensates for ageing of the infrared source and guarantees high reliability, long term stability and eliminates the need of periodical recalibration.
