- Real-time monitoring and alerts of the most common types of pollutants: H2S / CH4S, NH3, nmVOC, O3 / NO2, NO2, CO, SO2, PM10 & PM2.5 particulates
- Very high sensitivity to capture low level gas concentrations (down to ppb)
- Provides reliable measurement data at a fraction of the cost of reference method analyzers
- Evolutive, easy to use, easy to move: no cables or complicated installation, just set up and move to different locations on your site as needed
- Cairnet® requires only annual maintenance, when sensors should be replaced with new ones
- Ability to change the set of pollutants being monitored at any time (excepting dust)
- The Cairsens® sensors are manufactured in France and are calibrated in our metrological laboratory using Standard Reference AQMS monitors. No need for re-calibration (1 year lifetime). They are delivered with a calibration certificate.
- Embedded measurement of temperature, relative humidity and pressure
- Possibility to realize hybrid AQMS networks (reference stations & mini-stations)
- Measurements meet European directive 2008/50/EC
Independent reviewers, including the European JRC (Joint Research Council) and the US-EPA, have determined the accuracy, linearity, limits of detection and precision of Cairsens® as very good when compared with reference devices. Further studies with NASA have shown very good agreement with reference measurements.
Every Cairnet measurement point consists of:
- Solar panel and its battery
- Wireless communication module
- Weather protection enclosure including up to 4 Cairsens miniature sensors, each measuring one or two pollutants. Th sensors are to be selected from the list, function of your specific requirements.
