Aerosol Charge Neutralizer Model 9000

Description

A charge neutralizer that provides reproducible bipolar charge distributions in a very affordable & easy-to-maintain package.

The charge neutralizer produces a reproducible, bi-polar equilibrium particle charge distribution for scanning mobility sizer, electrostatic precipitator and particle charging experiments. With two Model 2U500 Polonium-210 sources, the neutralizer will operate for 3 years before new sources are needed. The unit may also be used to bring highly charged aerosol from atomizers and other sources to charge equilibrium to help reduce electrostatic losses.
