Overview
The Trek® 541A (pictured with the Model 541PR-S probe) electrostatic voltmeter is configured with a miniature electrostatic field chopper probe. The probe can be remotely located and easily positioned within process equipment. The unit's 20 x 4 alphanumeric LCD screen displays the present measured voltage, positive and negative peak voltage values, and additional menu information. Visual and audible alarms activate when preset voltage-threshold levels are reached.
