A reliable and fast measurement
COMPLIANCE AND ANTICIPATION
CAPELEC works alongside official organisations to define road safety standards. This involvement guarantees compliant, sustainable solutions that are aligned with regulatory developments.
After several years of research and specification within a European working group, Capelec has developed an innovative engine exhaust particle tester.

Daily maintenance and ease of use : impacts on operating costs and productivity.
REDUCED MAINTENANCE
No soot clogging and reduced maintenance
The cell design limits maintenance and consumables. Particles are sucked in by the Venturi effect using a clean air flow and electrostatically charged at the sensor inlet. This keeps the sensor clean and extends its service life.
Direct-flow design advantages:
- No filter
- No clogging or fouling
- No cleaning
- No consumables
- No recalibration
- Insensitive to shocks and vibrations
- High availability and extended service life
QUICK AND EASY MEASUREMENT
The operator follows the instructions on the screen and completes the procedure in 30 seconds.
- Intuitive interface
- Printable test report
- PASS/FAIL result
- Slow measurement, without polluting or noisy acceleration
ExtDC Advanced Diffusion Charging : Accurate and sensitive technology
ACCURACY AND REPEATABILITY
CAP3070 is an exhaust particle counter (PN) using Extended Diffusion Charging (ExtDC) measurement technology.
Extended DC goes beyond the Diffusion Charging process. It further increases the accuracy of results thanks to a concentration compensation algorithm.
- Wide measurement range
- Up to tens of millions of particles
- Very short response time
