Miniature Air Quality Monitoring Stations

SKU: Cairnet

Our Miniature Air Quality Monitoring Station (MAQMS) is an integrated system consisting of a miniaturized measuring cell, using a dynamic air sampling with a patented filter, and an electronic circuit allowing to measure and translate the smallest variations in concentration levels. Reliability of the measurement is achieved by limiting the effect of humidity variations by using a gas specific inlet filter combined and thanks to the dynamic air sampling system. The high quality of the miniature sensors provide specific measurements and their very low power consumption allow for long term monitoring. The MAQMS integration is available as autonomous or wireless communicating station with realtime data access. Together, they provide an affordable and reliable mean of monitoring ambient air emissions. Sensing is ensured by Cairsens from Environment SA Cairpol Sensors. The sensor has a built in datalogger capability and can be coupled to weather monitoring sensors allowing easy data collection. Many types of sensors and system configurations are available to meet various needs.
