Nissin Pulse Electronics
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 pulse waveforms.
The unique internal structural design of these high-voltage probes ensures that measurements of complex waveforms are not affected by electrostatic or electromagnetic interference.
