4700 Precision High Voltage Meter

4700

DC Accuracy 0.03%
AC Accuracy 0.12% True RMS
Direct Measurement Range Up to 10KV DC or AC
Extended Range (SmartProbes) Up to 140KV
AC Frequency Range 0.01 Hz – 600 Hz
Readings 60 filtered per second

Vitrek’s 4700 measures high voltage directly to 10KV DC or AC without external probes, with 0.03% DC accuracy and 0.1% True RMS AC accuracy that rivals traditional high voltage reference dividers. For production lines, calibration labs, and research facilities where high voltage measurement accuracy is the thing you cannot compromise on.

The 4700 is built around DSP technology that takes over 40,000 raw readings per second, filtered and scaled into 60 high-accuracy readings per second, stable on AC and DC simultaneously. A colour touchscreen displays both AC and DC content together and can chart readings from seconds to days, documenting HV drift, ramp time, overshoot, and sag on one screen.

SmartProbe™ inputs extend the direct 10KV range to 35KV, 70KV, 100KV, and 140KV without recalibration, each storing its own calibration data. Use one probe to extend range, or two simultaneously for differential or phase-to-phase measurement.

True RMS AC measurement covers 0.01 Hz to 600 Hz with 78dB noise rejection for stable readings in noisy environments. High-impedance G-series probes reach 30GΩ. An optional battery pack gives up to 11 hours of portable operation.

Overview

The 4700 is Vitrek’s precision high voltage meter: 0.03% DC accuracy, direct measurement to 10KV, and SmartProbe extension to 140KV, in a compact benchtop instrument. The calibration lab choice when high voltage measurement accuracy matters and the traditional reference divider is too fragile, too slow, or too much trouble.
