Hioki DT4223 Digital Multimeter 600V

Hioki DT4223 Digital Multimeter

The DT4223 is Hioki's compact everyday multimeter for electricians doing residential and light commercial work. Its key safety innovation is circuit breaker false trip prevention — a fast-blow fuse and current-limiting resistor combination that prevents the instrument from triggering ELCB/RCD trips when measuring in resistance mode, a common frustration with standard multimeters.

Key Features

• 6,000 count display
• ±0.5% DC voltage basic accuracy
• Circuit breaker false trip prevention — safe resistance measurement on live circuits
• Non-contact voltage (NCV) detection
• CAT IV 300V / CAT III 600V safety rating
• Compact 190g design fits in a tool bag
• IP42 dustproof and waterproof (while in storage)
• AC/DC voltage, resistance, capacitance, frequency, continuity, diode check

Applications

Home wiring checks, light commercial electrical work, control panel testing, HVAC servicing and any application where a compact, reliable multimeter is needed for standard electrical measurements. The NCV function provides a non-contact safety check before making direct measurements.
