Yes.
All new Zephyrs and Zephyr sensor cartridges from us are iMCERTS compliant on both the 10-second and 60-second sampling modes. If you have an older Zephyr and are unsure whether yours is, just ask EarthSense support.
Zephyr is iMCERTS compliant
Zephyr has been certified as compliant with the Performance Standards for Indicative Ambient Particulate Monitors against the UK Environmental Agency’s MCERTS Scheme (Indicative MCERTS). The certification provides end users with an extra level of confidence that its data quality for PM₂.₅ and PM₁₀ is accurate and reliable, meaning that Zephyr monitors are fit for certain regulatory purposes, such as identifying short-term pollution events at construction, demolition or waste transfer sites.
All cartridges are provided with a co-location certificate with detailed information about the performance of the sensors – NO₂, NO, O₃, PM₁₀ & PM₂.₅
