Aerosol electrometer for accurate particle charge measurements
In particle research and instrument calibration, precise measurements of aerosol properties like particle charge and concentration are crucial. Conventional measurement methods often lack the sensitivity and range required for accurate data collection, especially in applications involving submicrometer particles.
Measure aerosol charge and concentration reliably
The Aerosol Electrometer 3068B by TSI Systems is designed to provide precise measurements of electrical current and flow rate in aerosols, capturing total net charge on particles ranging from 0.002 to 5 µm. Ideal for calibrating particle instruments like Condensation Particle Counters, it enhances the accuracy of particle concentration measurements. The instrument features increased sensitivity (±1 fA) and a wide dynamic range (±12,500 fA), ensuring stable readings with reduced drift thanks to temperature stabilization. Compatible with modern communication interfaces like RS-232 and USB, it provides real-time data display and recording. Automatic flow control (0.3 to 10 L/min) and reduced internal particle losses further streamline its operation. When paired with a TSI Electrostatic Classifier, it delivers fundamental particle concentration measurements, making it a reliable choice for submicrometer filter-efficiency tests and charge ratio experiments.
