Datasheet
The Trek 520 voltmeters are not your typical hand-held field-meter. Their measurement technology provides surface voltage measurements that are essentially independent of the sensor probe-to-measured surface spacing. The Trek 520 is available in two versions: 520-1 and 520-2. The Trek520-1 has a digital meter to display the measured voltage. On the other hand, the Trek 520-2 has an analog output monitor in addition to the digital display. This analog output monitor can be used to record the measured voltage or to view it on an oscilloscope.
Features
Chopper stabilized for drift-free operation in ionized environments
NIST-traceable Certificate of Calibration provided with each unit
Benefits
Accurately measure surface voltage at a wide range of spacings
No need to maintain a fixed spacing
