Model 876 & 884 Electrostatic Voltmeter

Model 876 & 884 hand held electrostatic voltmeters provide accurate, noncontacting measurements of electrostatic surface voltage for ESD applications in either ionized or non-ionized environments. These two voltmeters 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.

APPLICATIONS
· 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
