- NH3 real-time monitoring
- Very high sensitivity to capture low level gas concentrations (down to ppb)
- Accurate measurement data at a fraction of the cost of Reference Analyzers
- No maintenance required during the Cairsens®’s lifetime
- No need for re-calibration during 12 months
- Embedded USB and UART / ModBus communication ports
- Up to 20 days of 1-minute data storage capacity
- Ultra-small, with close to zero power consumption
- Ready to use and easy to integrate
- Measurements meet European directive 2008/50/EC for indicators
Cairsens® are manufactured in France and calibrated in our metrological laboratory using Standard Reference AQMS monitors. Every sensor shipped includes a calibration certificate.
