Particulate measurement as part of the main inspection for Euro 6/VI vehicles with compression ignition engines will come into force on January 1, 2023. The counting of soot particles as an integral part of the exhaust emission test of diesel passenger cars. This is associated with specific requirements for the calibration process and conformity assessment for particle counting devices, according to the AU device calibration guideline [VkBl. 11/2021-No. 131]. In addition, VkBl. 24/2020-No. 190 requires the calibration of exhaust gas measuring devices by a service provider accredited according to DIN EN ISO/IEC 17025. We offer you a market-ready reference calibrator that meets these requirements.
The Knestel PN Reference Calibrator can be used to calibrate PN instruments of all types on site. It combines a highly stable salt generator and a reference particle counter in a portable housing.

“Self test error” | Contact Knestel for latest Software Updates |
No NaCl solution available | Refill NaCl solution and screw in |
Blocked nozzle | See next chapter |
Generator does not start | Check whether the solution in the NaCl container is “bubbling”. If not, restart the device, check whether the measuring mode is active. |
Nozzle of the salt particle generator clogged | Perform flushing function repeatedly Clean nozzle as in next chapter Clean (ultrasonic bath) or replace the nozzle of the salt particle generator. Perform the rinsing function after each use! |
Leakage | Check for leakage at the hoses and at the silica container. |
| Check NaCl solution, |
No/wrong NaCl solution present | Check NaCl solution, refill and screw in |
High humidity, condensing atmosphere | Perform temperature adaption prior to operation Assure no condensing conditions Let device operate at any concentration as long as required to reach the correct particle size Contact Knestel for latest product updates |
Rinsing function was not used at last operation | Perform rinsing function after each use |
Indication for Software issue | Contact Knestel for latest Software Updates |
