Hioki 3174 Hipot / Insulation Tester

Overview

The Hioki 3174 is a professional-grade hipot and insulation tester used for safety testing of electrical equipment and components. It combines both insulation resistance testing and high-voltage withstand voltage (dielectric strength) testing in a single instrument, with precise PWM-based voltage generation and remote control capabilities via RS-232C interface.

Key Features

• Continuous insulation testing at 500 V and 1000 V
• Withstand voltage testing with 100 VA transformer capacity
• Testing voltage range 0.2 V AC to 5.00 kV AC
• Digital voltage setting with 0.01 kV resolution
• Current measurement 0.01 mA to 20.0 mA with selectable ranges (10 mA and 100 mA)
• Sine wave operation (≤5% distortion) with 50/60 Hz selectability
• Voltage meter accuracy ±1.5% rdg. (≥1000 V) or ±15 V (<1000 V)
• Save up to 8 test settings each for withstand and insulation modes
• Contact check and full remote control via RS-232C
• GPIB interface available on Model 3174-01
• 1-year warranty included
