The plots below show the performance of Clarity Nodes when using both Global and Collocation-Based Collocation:
We are committed to transparency and scientific integrity, and recognize that air quality data performance specifications should reflect real-world conditions rather than idealized scenarios — that's why all of our performance results are for long-term collocations, rather than selectively showcasing only the best outcomes for short-term collocations, as is often the case in our industry.
Calibration is included free of charge as part of Clarity's Sensing-as-a-Service offering — we calibrate all air quality sensor data on behalf of our customers. After Onboarding, Clarity customers have the option to choose between pre-calibration using the Global Calibrations or Collocation-Based Collocation, as illustrated by the graphic below.
All Clarity Nodes come equipped with preset standard calibrations — the Global Calibrations — for both PM2.5 and NO2 measurements. This ensures that calibrated data are available even for organizations without access to a reference monitor or that choose not to perform collocation-based calibration.
While pre-calibration with Global Calibration significantly improves data performance, we highly recommend Collocation-Based Calibration for any air quality sensor network.
No separate software purchase. No add-on warranties. No unexpected expenses.
With one upfront service, we’re giving you the affordability, flexibility, and autonomy to eliminate all of your air quality blind spots.
Self-powered Clarity Node-S air quality monitoring hardware measures PM2.5 and NO2 and serves as a platform for additional modules that measure Wind, Black Carbon, and Ozone.
