SPCS-ONE Solid Particle Counting System

Particle-Number Measurement for Certification and Development

SPCS-ONE supports real-time SPN10 and SPN23 measurement for applicable emissions-certification procedures and advanced research and development. Flexible configurations allow particle-number measurement with full-flow dilution, partial-flow dilution, or direct sampling.

Applications include:

Engine and vehicle certification testing
Simultaneous particle-number measurement upstream and downstream of a gasoline particulate filter (GPF)
Development associated with Euro 7 and GB 7 requirements
Engine and aftertreatment development for hydrogen and alternative fuels
Particulate-filter evaluation and optimization
Piston-ring research focused on reducing oil consumption

Flexible Configurations for Different Sampling Requirements

SPCS-ONE is available in four sampling configurations. Select the model according to the dilution system, sampling location and testing objective.
