The last generation of Cairsens® micro-sensors for Particulate Matters (PM) monitoring operates without any influence from moisture in ambient air. They measure PM1, PM2.5 and PM10 concentrations.
The Cairsens® allow for continuous maintenance-free operation during their lifetime, even in highly polluted and humid atmospheres.
Thanks to their robust and miniature design, they are fully compatible with ENVEA’s turnkey AQMS station Cairnet®. They can also be easily embedded into a specific integration process.
