The APC xApp is available in four different configurations and suited to different applications.
The APC xCert is used for diluted exhaust gas sampling and supports the certification of Euro 6 standards for passenger cars according to UNECE-R83 or heavy-duty engine certification of EURO VI according to UNECE-R49 standards.
During engine development, you can use the APC xApp family to measure undiluted exhaust gases. It also has R&D applications in anticipation of the EU7 draft specifications with its 10nm PN size limit.

Accurate in Extremes of Altitude and Temperature
The xApp stands for multiple and extreme environmental conditions such as an operation range from –30 °C up to 45 °C and RDE altitude specifications up to 3,000 m (700 mbar).
Available in 4 Versions for Different Applications
- APC xApp for comprehensive coverage of all for 23 nm measurement tasks with diluted and raw exhaust.
- APC xCert for 23 nm measurements with CVS tunnels or partial flow dilution systems (PFDS).
- APC xApp 10 for draft EU7 R&D purposes for 10 nm measurements.
- APC xApp Dual for the PN measurement of 10nm and 23nm in parallel.
Serviceable Primary Diluter
The primary diluter is a patented “Chopper Diluter” allowing a wide dilution range under fluctuating inlet pressures and temperatures. Based on its compact and innovative design it can be serviced on-site in the R&D application.
