Electrostatic Classifier 3082

SKU: 308200

Our latest generation of Electrostatic Classifier, Model 3082, continues to be the solution in helping scientists generate and size submicrometer particles. The Classifier features valuable capabilities for many aerosol-related applications, and an easy-to-use interface.

Product Details

Since 1976, TSI Electrostatic Classifiers have been helping scientists generate and size submicrometer particles. These instruments have been used in a wide variety of research areas, and have earned a well-deserved reputation for being highly reliable and extremely versatile. The current design offers tool-free installation and auto-detection of configurable components. The Electrostatic Classifier serves as the controller platform for high-resolution submicrometer sizing. Select one of our four DMAs to achieve the desired size range. Combine with one our Condensation Particle Counters to obtain a Scanning Mobility Particle Sizer system.
