Measurement can be made of peak values with rise time of less than one millionth of a second. The Model PRM Voltmeter is portable and is ideal for use in the field or laboratory, for measuring the output voltage of spark type Holiday Detectors.

The Model PRM may also be used in design or production testing to measure ignition voltages, over-voltages caused by switching of electrical circuits and other voltages that often accompany high potential testing. Absolute high tech integrated circuitry assures dependability and virtually eliminates maintenance.
