Accredited Particles

Using accredited particles—such as Certified Reference Materials (CRMs) or monodisperse Polystyrene Latex (PSL) spheres produced under ISO 17034 or ISO 17025 guidelines—ensures that aerosol particle counter calibrations achieve the highest level of metrological traceability, sizing precision, and regulatory compliance.

We now offer a range of accredited particles in the following sizes.

100 nm (0.1µm)
200 nm (0.2µm)
