Particle emissions are a critical component of engine emissions measurements

Researchers and vehicle manufacturers around the world use TSI engine emissions particle counters for certification testing, emission research, and in-use diesel particulate filter (DPF) performance checks.

TSI’s engine emission particle counters predate—and helped to define—the UN-ECE Particle Measurement Programme (PMP). Our Engine Exhaust Condensation Particle Counter (EECPC) detects particles 23 nm in size and larger, as mandated by Euro 5/6 (V/VI) regulations. The Nanoparticle Emission Tester (NPET) is ideal for measuring solid particle emissions due to its built-in catalytic removal of volatile particles and dilution system. Customers use the NPET on non-road mobile machinery to comply with Swiss regulation 941.242 as well as for other emission tests; for example buses on route can be checked within 5 minutes.
