The Model 3068B Aerosol Electrometer provides accurate measurements of current and flow rate. It measures the total net charge of aerosol particles from 0.002 to 5 μm in size.

When the Aerosol Electrometer is used with a TSI Electrostatic Classifier, it measures the concentration of monodisperse aerosols. This configuration is primarily used to calibrate and test particle instruments such as Condensation Particle Counters.

Data is displayed on the front panel display and output in real time via RS-232 or USB, and is also used as a datalogging analog voltage. Vacuum source essential
