DT4224 Digital Multimeter

• 4-digit display, bar graph
• low-pass filter for high harmonic suppression
• operating temperature: -10°C - 65°C

Detailed Product Overview

The HIOKI DT4224 is a universal pocket digital multimeter designed for a wide range of electrical measurement tasks. In addition to AC and DC voltage checks, it supports resistance, capacitance, frequency and diode testing, making it well suited as a first tool for troubleshooting and initial analysis in both field and workshop environments. 

With its compact design, the DT4224 takes up very little space in a tool bag or pocket. With battery installed and test leads connected, it weighs approximately 210 g, making it easy to carry for everyday work. Powered by a single AAA battery and protected by a silicone cover, it is suitable for regular use in installation, service and workshop applications. 

Measurement Ranges and Safety

The DT4224 is equipped with a clear 6000 count display and an intuitive operating concept that supports efficient troubleshooting and verification tasks. AC and DC voltage ranges from 600 mV to 600 V cover a wide range of measurement situations, from low level signals to mains voltage. With measurement categories up to CAT III 600 V and CAT IV 300 V, it is suitable for work on distribution boards and fixed installations.

For safe troubleshooting in active circuits and complex electrical installations, the instrument is equipped with an integrated protection function that prevents false tripping of circuit breakers in case of measurement errors. If measurements are accidentally performed in the resistance or continuity mode on an active circuit, or if the measurement function is changed with test leads connected, the input impedance remains high. The input is only switched to a low impedance state once the measurement condition is recognized as safe

Although extremely compact, the DT4224 is a high quality digital multimeter designed for professional installation, service and troubleshooting work. Like all HIOKI digital multimeters, the DT4224 is developed in Japan and manufactured at HIOKI’s own production facilities in Japan.
