Features
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.

*2: MEXA-2300SPCS can be used in the measurement method according to the regulation. For detailed information, please contact HORIBA.
*3: Dilution factor of the system should be determined so that the particle concentration after dilution fits into the measuring range.
*4: Allowable range of gas temperature at sample probe inlet depends on the sampling condition, because it is limited as the temperature of diluter in DSU (350 °C or less). For detailed information, please contact HORIBA.
*5: Accuracy of dilution factor check with span gas.
*6: The dimensions depend on customers.
Engine testing in automobiles and components
Catalyst testing in automobiles and components
Brake Dust Measurement
A series of legislative measures has significantly reduced the amount of emissions that is being emitted by internal combustion engines of light and medium-duty vehicles.
Particle Measurement in the Sub-23nm Range
Concerns exist that advances in modern engine technology may contribute to large portions of solid particles at sizes smaller than 23nm. The EU Joint Research Center has confirmed this concern in several investigations.
