MEXA-1000 SPCS - Solid Particle Counting System

Application Able to take raw sample from engine tailpipe, as well as diluted sample from tunnel-CVS. Applicable to after-treatment system evaluation, by taking sample gas from upstream and downstream of catalyst to check efficiency. Performance Two-stage dilution by Wide Range Continuous Diluter ( WRCD) ; Developed by HORIBA - Patent applied. Dilution ratio: Primary diluter: 10 to 1000 Secondary diluter: 10 to 50 Dilution accuracy: typically within ± 5% ( confirmed standard gas) Removal efficiency of volatile particle: 99% or higher ( at CPC inlet) Penetration of solid particle: 95% or higher at CPC ( based on poly-disperse) High repeatability of measurement Based on PMP New Standard ( Draft) The configuration of HORIBA solid particle counting system conforms to the recommendation by the Particle Measurement Program ( PMP) in Working Party on Pollution and Energy ( GRPE) under the auspices of United Nations Economic Commission for Europe ( UN ECE) . The system performance also meets with the requirements of the PMP draft standard, which has a high possibility to affect future regulations in other countries. The reliability of the system has been demonstrated by cross-checking with the PMP standard system, so-called " golden system" that participates in the Inter-Laboratory Correlation Exercise arranged by PMP.
