Electrostatic Classifiers and DMAs

These instruments work together to use the electrical mobility technique to determine particle size. This technique is the most appropriate way to measure the size of particles smaller than one micrometer. Indeed, ISO 15900 states that electrical mobility is the preferred mechanism, globally, for submicrometer particle measurement.

TSI’s electrostatic classifiers and DMAs have a long history, over 40 years, of using the electrical mobility technique to measure particle size. With decades of experience manufacturing high-performance aerosol instrumentation, classifiers and DMAs are at the heart of what we do.
