HEPaC

Handheld Emission Particle Counter

Researchers at the FHNW have developed a portable device for checking Diesel particle filters based on the naneos Partector 2.
This device, called HEPaC, will be available in the third quarter of 2022. It is METAS-certified for the Swiss market.

Benefits

The 7 key benefits of the HEPaC are:

 Simple measurement of particle number concentrations
 Portable and battery-operated
 Emission measurements without dilution (sensor heated)
 Concentration range up to 5'000'000 particles/cm3
 No operating fluids or dryers necessary
 Automatic creation of an official measurement report on a tablet
 METAS-certified according to ordinance SR 941.242
