Product Introduction

The Hioki DT4200 Digital Multimeter Series consist of a complete lineup of 9 models ranging from professional to industrial to pocket meters, delivering a super fast response rate and safety features that take electrical testing to a higher level. The DT4254 is a voltage measurement only model designed for measuring photovoltaic modules and other high-voltage targets up to 1700 V DC.

  • High-voltage measurement digital multimeter that measure up to 1700 V
  • Test no-load voltage at megasolar installations
  • Polarity detection and notification
  • Measure output voltage on the secondary sides of inverters by eliminating harmonic components
  • Measurement data can be downloaded to, reviewed on, and saved to a computer.
  • True RMS measurement for accurate measurement of even distorted current waveform
  • Designed and manufactured in Japan to ensure high quality and guaranteed with a 3-year warranty for peace of mind
  • Safe measurement requires use of an instrument that suits the measurement location.

Product Features

  • The voltage measurement model, which is ideal for solar power system and power equipment management, measures up to 1700 V DC during open voltage inspections (DT4254)
  • Prevents accidents with clamp-on sensor-based current measurement (DT4254, DT4255)
  • Voltage detection function (DT4254, DT4255)
  • Low-pass filter cuts high harmonics (when measuring inverter fundamental waveforms)
  • Broad -25°C (-13°F) to 65°C (149°F) operating temperature range (DT4254, DT4255)
  • Dual display lets you check voltage and frequency simultaneously
  • CAT IV 600 V, CAT III 1000 V
