The project objective was to develop a particle counter for measuring the exhaust gas of Euro 6/VI vehicles with compression ignition engines. The particle counter uses the clean-charging technology and is designed to charge clean air, thus avoiding contamination of the corona needle. The needle can also be easily changed via a service opening in the non-custody-transfer part. The particles are measured without contact using a Faraday cup. Of course, the device meets the PTB-A requirements and can therefore be used throughout Europe without any concerns.
The sensor technology has been subjected to type testing in the Netherlands (NMI) and Germany (PTB).
