Nanoparticle counter for ambient air monitoring with integrable NAFION® aerosol dryer (optional) for up to 104 particles/cm3 (single count mode)

The ENVI-CPC 50 is a butanol-based particle counter with high efficiency, especially for the smallest nanoparticles. It can monitor concentrations of ultrafine particles (UFP) in outdoor air. The Model 50 is designed for concentrations up to 104 particles/cm3. This makes it ideal for long-term measurement- alone or as part of an overall system for measuring the size distribution and concentration of UFP.

The patented evaporator and condensation module is maintenance-free. This allows continuous operating times of up to one year without maintenance and cleaning - unique so far.

The system meets the requirements of the standard CEN / TS 16976:2016 (Harmonized measurement of number concentrations using CPC) in all areas. It can be operated directly with a NAFION® based sampling system if desired. The pumps required for this are already integrated.
