The Praxis/Urban Air Quality Monitor
Cirrus Research has partnered with South Coast Science, experts in air quality monitoring, to offer you the best out‐ of‐the‐box solution for urban air quality monitoring.
The Praxis/Urban answers both the challenge of capturing accurate data in variable climate conditions and the need for fine‐grained air quality monitoring networks. The Praxis/Urban is ideal for gas and particulate monitoring for roadside monitoring, environmental health and local authority investigations. Integrate with the Quantum Cloud from Cirrus Research so you can view the air quality data you need 24/7, on any device, anywhere in the world.
