Non-Contacting, Hand-Held Electrostatic Voltmeters

Advanced Energy’s Trek 876 (±2 kV) and 884 (±20 kV) hand-held electrostatic voltmeters provide accurate, non-contacting measurements of electrostatic surface voltage for ESD applications in either ionized or non-ionized environments.

• Measurement Range 
  • 876 Range : 0 to ±2 kV DC
  • 884 Range : 0 to ±20 kV DC
• Recommended spacing
  • 876: 5 to 25 mm
  • 884: 30 to 60 mm

Overview

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.
