The Trek® 520 (±2 kV) and Trek 523 (±20kV) hand held electrostatic voltmeters that utilize a measurement technique that overcomes the disadvantage of the typical hand held field meter by providing surface voltage measurements which are essentially independent of the sensor probe-to-measured surface spacing.
Typical Applications Include:
    - Measurement of electrostatic surface charge build up
 
    - Manufacturing processes
 
    - Electronic assembly testing
 
    - Semiconductor material testing
 
    - Dissipative material testing
 
    - Automotive electronics testing 
 
    - ESD Auditing and troubleshooting
