Sensirion's particle sensor is a product that has obtained mCERTs certification, which is the standard of the British Environmental Monitoring System. The measurement principle of Sensirion's particle sensors is based on laser scattering and employs antifouling technology. This technology, along with high-quality, durable components, enables high-precision measurements over ten years of operation.

PM2.5 represents a fine dust category with particle sizes up to 2.5 microns and is present in the majority of air pollution. Sensirion's particle sensors enable air purifier manufacturers to offer products that help prevent long-term health hazards from air pollution.

■ mCERTs certification

The mCERTs certification for Sensirion's particle sensors proves their performance as PM sensors.
In addition, this certification facilitates integration into applications that must comply with the European air quality standard DIN EN 15267.
The mCERTs accreditation scheme was created by the UK Environment Agency and is built around international and European standards to ensure high quality environmental data monitoring.
The particle sensor has been proven in laboratory and field tests to meet mCERTs and the relevant DIN EN 15267 European air quality standards.
Compliance with the above criteria requires low intra-model variability (≤ 5 µg/m3).
This certification is issued by the Sira Certification Service, one of Europe's leading recognized bodies.
The organization is also accredited under ISO/IEC 17065 UKAS and is part of the Canadian Standards Association (CSA Group).
