Trek 323 Series Highly Sensitive, Versatile Electrostatic Voltmeter

The Trek® 323 features adjustments to compensate for many sensitive testing conditions. The response speed control adjusts the speed/noise tradeoff of the AC response. While the drift/spacing null adjustment minimizes the variation in zero-offset voltages as the probe-to-test surface spacing changes. 

Features

• Sensitivity: 5 mV
• Drift spacing/null adjustment
• Response speed control
• Additional probes available

Benefits

• Utilize low impedance probe sensor that assures high accuracy in high humidity and contaminated environments (e.g. airborne dust, toner, ions, and chemicals)
• Monitor detected output voltage through a 1:1 voltage monitor output and a switch-selectable scale of 10:1 or 20:1 voltage monitor output
• Use with various shaped probes (e.g. round, square)
