Product Details

The Model 3782 Water-based Condensation Particle Counter (WCPC) detects airborne particles down to 10 nm. Using single particle detection with continuous, live-time, coincidence correction, the Model 3782 measures particle concentration up to 50,000 particles/cm3 with high accuracy. Therefore, this WCPC is quite versatile and well-suited for a broad range of applications. These include basic aerosol research, indoor air-quality measurements, environmental monitoring, atmospheric and climate-change studies, and mobile aerosol studies.

The Model 3782 uses water vapor to enlarge particles for easy detection by an optical detector. It also offers fast response to changes in aerosol concentration, a high sample flow rate for good counting statistics, and a user-selectable lower detection limit (10 nm or 20 nm). Particle concentration, total counts, or plots of concentration versus time can be displayed on the front panel. Additionally, the Model 3782 can be used as part of a TSI Scanning Mobility Particle Sizer™ (SMPS™) spectrometer.
