CEN/TS 17660 Class 1: see the data behind Kunak's sensors

CEN/TS 17660-1:2021 (gaseous pollutants) and CEN/TS 17660-2:2024 (particulate matter) set a common European protocol to test sensor systems against reference methods and assign them Class 1, 2 or 3. Request verifiable information on how Kunak's sensors meet Class 1 requirements for the pollutants in your project.

Once you fill in the form, Kunak's sales and technical team will contact you and show you the test data that supports it, pollutant by pollutant.

  • Class 1highest class, linked to indicative measurements
  • 2 partsgaseous pollutants (2021) and particulate matter (2024)
  • ≥ 40 daysper field campaign alongside reference methods
  • 8pollutants across both parts, each classified separately

What we will show you

Verifiable information on how Kunak's sensors perform under both specifications, backed by test data, so you can judge whether they suit your project.

  • Pollutants assessed: O3, NO, NO2, CO, SO2 and benzene in part 1; PM10 and PM2.5 in part 2.
  • Laboratory and field tests: how they were run, including test routes, number of units, campaign duration and data capture.
  • Classification results: expanded uncertainty at the limit value, slope, intercept and dispersion between units.
  • Directive (EU) 2024/2881: how the new limit values affect the reading of each class.
  • Supporting data: the results behind each declared class, so you can verify it yourself.
