Engine Exhaust Spectrometer - 3090

Engine Exhaust Spectrometer
Enlarge Image+

The Engine Exhaust Particle Sizer (EEPS™) spectrometer measures the size distribution of engine-exhaust particle emissions in the range from 5.6 to 560 nm with the fastest time resolution available. Users can visualize and study the dynamic behavior of particle emissions that occur during transient test cycles, during the first few seconds of a cold start, or during regeneration of a particle trap or diesel particulate filter (DPF).

The EEPS spectrometer displays measurements in 32 channels total (16 channels per decade). It operates over a wide particle concentration range, including down to 200 particles/cm3. It operates at ambient pressure to prevent evaporation of volatile and semi-volatile particles, and it requires no consumables.

Ease of operation is a key feature of this particle sizer. All components are housed in a single 32-kg cabinet that includes the vacuum source. A microprocessor measures temperature and barometric pressure automatically to convert to volumetric flow. The instrument includes features for remote operation and includes software that is unmatched in the industry.
