The Cairsens© sensor allows specific pollutant measurement comparable to reference methods. The high quality sensors are renowned worldwide by our customers looking for the newest technologies in air quality monitoring.
They offer precise and reliable measurement, and are calibrated using a reference-standard value. They come with a unique calibration certificate and don’t need any more calibration after installation during their lifetime (12 months).
Excellent measurement accuracy is achieved by limiting the effect of humidity interference by using a specific and patented inlet filter combined with dynamic sampling
