Engine exhaust PM/PN particle size concentration distribution measurement device [*Demo unit available for loan*]
The "Model 3090 Engine Exhaust Particle Sizer (EEPS) Spectrometer" is a nanoparticle size distribution measurement device that measures particles ranging from 5.6 to 560 nm with a total of 32 channels of resolution. Similar to TSI's SMPS, it classifies particles using their electrical mobility, but instead of a CPC, it uses a multi-stage low-noise electrometer as the detector. This allows for particle size distribution measurements with a high temporal resolution of 0.1 seconds, enabling real-time observation of changes in particle size distribution. 【Features】 ■ Real-time measurement ■ Wide particle size range ■ Easy operation ■ Compatible with a wide concentration range ■ High sample flow rate ■ No neutralizer required *For more details, please refer to the PDF document or feel free to contact us. We also offer demo units for loan.
