Trek 320C
High Sensitivity, DC-Stable Electrostatic Voltmeter, Measures 0 to ±100 V DC or Peak AC
Designed to adjust to sensitive testing conditions, Advanced Energy's versatile Trek 320C is ideal for a variety of electrostatic applications. It offers highly accurate, non-contact measurement of
electrostatic potentials from 1 mV to 100 V.
- Measurement Range: 0 to ±100 V DC or peak AC
- Measurement Accuracy: Better than 0.05% of full-scale
- Speed of Response (10 to 90%): Less than 300 ms for a 100 V step

Overview
The Trek® 320C can be used over a wide range of probe-to-surface distances. It features a calibrated null voltage supply of ±10 V of nulls contact potentials when measuring voltages on dissimilar materials. Response speed control adjusts the speed/noise tradeoff of the AC response. And self-locking drift/spacing null adjustment minimizes the variations in voltage values as the probe-to-test surface spacing changes.
Benefits
- Use over a wide range of probe-to-surface distances
- Rely on response speed control to adjust AC response for speed and noise
- 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
Features
- 1 mV sensitivity
- Self-locking drift/spacing null adjustment
- 3.5-digit LED display
