Electrostatic Voltmeter TREK 542A

Description

The Trek Model 542A Electrostatic Voltmeter (pictured with the Model 542P-S probe) provides accurate noncontacting measurements of the electrostatic surface voltage associated with EOS/ESD processes. The instrument is configured with a miniature electrostatic field chopper probe that can be remotely located and easily positioned within process equipment to provide highly accurate, non-contacting, DC-stable, spacing-independent voltage measurements in either ionized or non-ionized environments. A 20×4 alphanumeric LCD screen displays the present measured voltage, the positive peak voltage value, the negative peak voltage value and additional menu information.
