Our measurement modules for particle measurement are based on diffusion charging (DC) technology. This is a particle counter based on the diffusion charging principle. The Advanced DC measurement is a two-step process, which consists of the charging of aerosol particles in the first step and the downstream measurement of a current induced by the charged particles.
The measurement principle is based on the accumulation of charge carriers on the particles. The formation of the charge carriers is realized by ionization by means of corona discharge. The gas ions attach themselves to the aerosol particles by diffusion. Thereby a particle size dependent electrical diffusion charging takes place. The charged particles induce an electric current in the sensor module, which can be measured.
Legal requirements & PTI: Particle measurement (PN) in diesel exhaust gases is increasingly being integrated into regular testing procedures. The aim is to reliably detect defective or manipulated particle filters.
Health & environment: Ultrafine particles penetrate deep into the lungs. Precise particle counting supports emission reduction and air quality targets.
Safety & reliability: Modern particle measuring devices deliver reproducible results – even at very low particle concentrations.
All diesel cars with particulate filters from Euro 6d (approximately from 2021) are subject to particle count measurement during the emissions test. In future, petrol cars with direct injection could also be covered – corresponding pilot projects are already underway.
The PNC nano is a ready-to-use diesel exhaust particle counter leveraging Clean Charging Technology and Faraday Cup contactless detection. It complies with PTB‑A certification standards and is type‑tested in Germany (PTB) and the Netherlands (NMI). The PNC nano is a precise particle measuring device used in exhaust gas testing. Further information can be found here.
An assembly of functional sensor modules (e.g. charging unit, ion/particle separator, sensor Faraday Cup, Volatile Particle Remover). Customers can build their own housing around this proven, tested sensor structure and connect via RS‑232 (CAN available on request). Further information can be found here.
A portable, market-ready calibrator combining a stable salt (NaCl) generator and a reference particle counter in one unit. It supports on-site calibration of multiple PN devices, ensuring traceability (EN 17025) and compliance with German AU calibration regulations effective since January 1, 2023. Further information can be found here.
The system employs diffusion charging (DC): aerosol particles are ionized via corona discharge, then charged through diffusion. The charged particles induce an electrical current in the Faraday Cup sensor module, which is measured—without consumables or sample gas heating. This enables precise particle counting without the need for emission tester with moving parts.
Many markets are gradually introducing PN measurement or have already integrated it. Concrete requirements are regulated on a country-specific basis. In Germany, particle measurement is already part of the exhaust emission test (AU) carried out as part of the general inspection (HU).
A particle counter records the number of ultra-fine particles (PN) in the exhaust gas – not the mass. This is particularly effective in detecting defective or manipulated particulate filters.
Yes – we also offer our systems as OEM modules with standardized interfaces (CAN, Modbus, analogue). This means that particle measurement can be easily integrated into existing test benches, software solutions or test devices.
