Air, Weather & Dust MonitorsCirrus 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. With the South Coast Praxis OPCube you can detect critical environmental pollutants and particulates
- Measures fine dust and ultrafine particles with sizes PM1, PM2.5, PM10
- Up to one-hour operation in the event of external power loss
- Detects one gaseous pollutant including CO, H2S, NO, NO2, O3, SO2, VOCs or CO2
The Praxis/OPCube 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/OPCube answers both the challenge of capturing accurate data in variable climate conditions and the need for fine‐grained air quality monitoring networks. The Praxis/OPCube 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.
With the South Coast Praxis OPCube or Urban air quality monitor, you can detect critical environmental pollutants and particulates, including respirable particles with sizes PM 1, PM 2.5 and PM 10 (MCERTS certified for PM2.5 and PM10). These gases and particulates are found in vehicle and motor exhausts, smoke from burning oil and coal, and dust from demolition, construction, and quarrying.
