Cairsens - new generation of air quality & odors monitoring sensors - 1

Miniature solution for real-time continuous pollution monitoring AIR QUALITY MONITORING SYSTEMS “40 years of experience in the field of environmental monitoring to the benefit of our micro-sensors” 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. Most of the Cairsens© sensors use amperometric technology consisting of three electrodes: the working electrode (anode), the counter electrode (cathode) and the reference electrode. The gas to be analyzed is diffused through a permeable membrane towards the sensitive electrode. The function of the gas, oxidation takes place at the anode, or reduction at the cathode. The electrical signal generated between the two electrodes is proportional to the concentration. Excellent measurement accuracy is achieved by limiting the effect of humidity interference by using a specific and patented inlet filter combined with dynamic sampling. MAIN BENEFITS: R eal-time monitoring of the most common types of pollutants: NO2, O3/NO2, CO, SO2, PM10 & PM2.5, H2S/CH4S, NH3, nmVOC V ery high sensitivity to capture low level gas concentrations (down to ppb) Accurate measurement data at a fraction of the cost of Reference Analyzers N o maintenance and no need for re-calibration (1 year lifetime) E mbedded USB and UART / ModBus communication ports U p to 20 days of 1-minute data storage capacity U ltra-small, with close to zero power consumption R eady to use and easy to integrate M easurements meet European directive 2008/50/EC for indicators Data download via computer

RELIABILITY AND ACCURACY Independent reviewers, including the European JRC (Joint Research Council), the LCSQA and the US-EPA, have determined the accuracy, linearity, limits of detection and precision of Cairsens® as very good when compared with reference methods. Further studies with NASA have shown very good correlation with reference measurements. Correlation of measurements: Reference station vs Cairsens NO2 (ppb) NO2 measurement comparison: Traffic reference-station vs 3 Cairsens O3 monitoring, comparative test: Cairsens vs Reference method “ Great correlation between measurements of...
