Hioki DT4254 Digital Multimeter



Digital Multimeter With Fuse-Protected Terminals Ideal For Harsh Work Environments

The DT4254 is a voltage measurement only model designed for measuring photovoltaic modules and other high-voltage targets up to 1700 V DC.

CAT IV 600 V, CAT III 1000 V

Key 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
