Aerosol electrometer for accurate particle charge measurements
Achieve precise particle charge measurements and enhance your calibration processes with this advanced aerosol electrometer, designed for reliable, real-time data acquisition in aerosol research and air quality monitoring.

Measures Particle Charge and Concentration
The Aerosol Electrometer 3068B from TSI Incorporated offers unmatched precision in measuring electrical current and flow rate of aerosol particles, ranging from 0.002 to 5 µm. Paired with a TSI Electrostatic Classifier, it excels in calibrating and testing particle instruments, crucial for nanotechnology and environmental sciences. Outputs are available via RS-232 and USB, providing real-time data critical for particle charge and concentration studies. It boasts a wide dynamic range (±12,500 fA) and increased sensitivity (±1 fA), outperforming its predecessor, Model 3068A. Designed for easy integration into existing systems, the electrometer’s automatic flow control (0.3 to 10 L/min) and temperature stabilization minimize drift, ensuring reliable long-term measurements. Ideal for use in pharmaceutical, chemical, and air quality testing industries, it supports operations in continuous and bench-top modes. The device requires a vacuum source for operation and is integral to submicron filter-efficiency tests and emission testing applications.
