Real-time measurement of mist and powders can be performed even under high temperature and high pressure conditions (compatible with high concentrations).
The "welas (White Light Aerosol Spectrometer)" developed by PALAS is an aerosol spectrometer that uses a white light source. The new model, the "welas digital series," is equipped with a high-speed 20 MHz signal processor that analyzes continuous individual particle signals. This new technology reduces coincidence errors in light scattering measurements, allowing for the identification and correction of individual particles. It is now capable of measuring even higher concentrations compared to previous models. 【Features】 ■ Smooth calibration curve using a white light source and 90-degree scattered light ■ Fine classification channels and sharp classification characteristics ■ Detection particle size range of 0.2 to 105 μm (varies by sensor) ■ High concentration particle counting up to 10 to the power of 6 particles/cc *For more details, please refer to the PDF document or feel free to contact us.
