Water-based Condensation Particle Counter

Model 3785

The Model 3785 Water-based Condensation Particle Counter

(WCPC) is a general-purpose counter that can detect airborne

particles down to 5 nm in diameter. It detects these particles

over a wide concentration range from 0 to 107 particles/cm3, at

a high aerosol-sample flow rate of 1.0 L/min. As a result, this

WCPC is versatile and well-suited for a broad range of

applications, including basic aerosol research, indoor air-quality

measurements, health effects research, inhalation and exposure

studies, atmospheric and climate studies, and nanotechnology

research. Additionally, it can be used as part of a TSI Scanning

Mobility Particle Sizer™ (SMPS™) spectrometer.

Applications

TSI offers the most comprehensive line of CPCs available.

Building on a tradition of 30 years experience, TSI CPCs have

become the standard to which all others are compared.

General applications include:

 Basic aerosol research

 Filter and air-cleaner testing

 Atmospheric and climate studies

 Particle formation and growth studies

 Combustion and engine exhaust studies

 Inhalation or exposure chamber studies

 Health effects studies
