The Model 3068B Aerosol Electrostatic Meter provides accurate detection of current and flow rate. It detects the total net charge of aerosol particles from 0.002 to 5 μm in size.

When the Aerosol Electrostatmeter is used in conjunction with the TSI Electrostatic Classifier, the concentration number of monodisperse aerosols can be measured. This configuration is primarily used for calibrating and testing particle instruments such as condensation particle counters.

Data is shown on the front panel display and output in real time via RS-232 or USB and is also used as an analog voltage for data logging. Vacuum source essential
