MEXA-2000SPCS series
Vue d'ensemble
The HORIBA MEXA-2000SPCS series measures the number of solid particles from engine exhaust gas in real-time.
The series can complete engine/vehicle certification testing in the latest
regulations (Euro 5/6 and Euro VI), which requires complied dilution systems,
along with R&D testing of engines and particulate filters by direct sampling
without dilution.
- Certification tests for Euro 5/6 and Euro VI
MEXA-2000 / 2200SPCS - Tests with a partial flow dilution tunnel connected
MEXA-2200 / 2300SPCS - R&D tests with high pressure direct sampling
MEXA-2100 / 2300SPCS - Sub-23 nm particle measurement [New Lineup]
(Specification required in 74th UNECE GRPE session on January 11, 2017.)

*2:Direct sampling at a pressure less than 5 kPa is possible. Acceptable maximum concentration is limited to the same value as the full flow tunnel.
*3:A DSU predilution unit with pressure adjusting function realizes direct sampling for high pressure applications of up to 100 kPa.
Fonctions
Compact design
• Easy to install and transport in a laboratory
• Small footprint
High performance sampling system
The set DF is not affected by changes in sample pressure in the CVS or
sampling system. The VPR *1 calibration factor (PCRF *2) can be used
for many applications without specific calibration/correction of the diluters
in VPR.
*1 VPR: Volatile Particle Remover
*2 PCRF: Particle Concentration Reduction Factor
Various optional units
The combination of the main unit and optional units allows a wide range of applications and sampling configurations.
