Overview

The standard models of NPE high-voltage probes include: EP-50K, EP-100K, EP-150KP.

They can measure any high-voltage signals, including DC, AC, and pulsed waveforms.

The unique internal structural design of these high-voltage probes ensures that when measuring complex waveforms, they are not affected by electrostatic or electromagnetic interference.
