Miniature solution for real-time continuous NH₃ monitoring

Cairsens® NH₃

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.

Excellent measurement accuracy is achieved by limiting the effect of humidity interference by using a specific and patented inlet filter combined with dynamic sampling.

NH3 micro-sensor
Add to Compare
  • NH3 real-time monitoring
  • Very high sensitivity to capture low level gas concentrations (down to ppb)
