Trek 876 and 884 Series


Non-Contacting, Hand-Held Electrostatic Voltmeters

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. 


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


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


Operational temperature range (°C): 15 to 35
Measurement Range: 0 to ±20000 V
Measurement Accuracy (%): +/- 5%
