The Trek® 876 and 884 electrostatic voltmeters offer a distinct advantage over other handheld fieldmeters. They can provide accurate surface voltage measurements that are independent of sensor-probe-to-measured-surface spacing. They can be used for a variety of applications including electronic assembly testing, semiconductor material testing, and many more. 

*Always use the original grounding cord without any safety resistor; failure to do so will lead to measurement errors.


  • Accurately measure surface voltages
  • No need to maintain fixed spacing
  • Use in ionized or non-ionized environments


  • Chopper stabilized for drift-free operation in ionized environments
  • NIST-traceable calibration certificate provided with each unit
  • Features 3.5-digit, liquid crystal display

Select specifications are shown below. Please see product data sheet for additional specifications.
