Air quality measurement equipment trusted by organizations like:

Elisha Mulilo

Air Quality & Emissions Specialist, Kansanshi Mine

“There's less maintenance with Clarity’s compact Node-S device — that means less cost to actually go to that particular site. That time and cost-saving measure is critical for our business.”

Bill Hayes

Air Quality Program Coordinator, Boulder County Public Health

"After the Marshall fire we installed a total of 22 monitors in the burn area. The Node-S is solar powered, has impressive battery-life and transmits data via cellular network. That means we could put these monitors anywhere that the sun shines and that you can make a cell call."

Matt Holmes

Air Quality Consultant and former Executive Director, Groundwork Richmond

"We couldn’t have done it with any other air quality monitoring solution. With their unique ability to operate off-grid, Clarity’s Node-S provided the ability to site our air quality monitors in the locations that mattered most to community members in Richmond. The data are reliable, real-time, and hyperlocal, and our network is now being used as a blueprint for AB 617, a landmark regulation that empowers communities to take control of air pollution."

Eddie Ahn

Executive Director, Brightline Defense

"Clarity was our first-choice air quality monitoring provider for several reasons. We enjoyed working with the Clarity team - they are highly knowledgeable and always responsive. The Node-S devices themselves are also incredibly resilient, which was especially important for us when deploying the monitors in emergency conditions during the wildfire events this past year."

William Chevalier

Supervising Air Monitoring Specialist, Monterey Bay Air Resources District

"We were excited when we saw what Clarity was offering — it works very nicely for our objectives with the wildfire air monitoring network. We liked that Clarity’s sensors are very quick to install and very easy to use, thanks to the native solar panel and cellular antenna. Not having to use somebody else's WiFI in a remote location is great — that had been a major issue for us with several projects.”

Node-S colocation

Buy pre-calibrated air quality sensors or collocate in the field

Accurate air quality monitoring starts with calibration. Clarity's rigorous Collocation and Calibration process ensures your air pollution measurements are scientifically validated and defensible.

Purchase Node-S devices pre-calibrated to generalized models by the Clarity Lab, or collocate anywhere with a reference monitor to develop custom localized calibrations — all included with Sensing-as-a-Service℠ air quality monitoring.
