Product Description
The Hioki DT4221 Pocket Digital Multimeter is designed for electricians and technicians working in higher-energy electrical environments where safety certification is an important consideration. As part of Hioki's DT4200 series, the meter combines a compact pocket-sized design with CAT IV 300V and CAT III 600V safety ratings.
The DT4221 measures DC voltage from 600.0mV to 600.0V across four ranges, with an accuracy of ±0.5%. AC voltage measurement covers 6.000V to 600.0V across three ranges, with a 40Hz to 1kHz frequency bandwidth. The meter also supports frequency measurement from 99.99Hz to 9.999kHz.
A built-in voltage detection function provides a convenient way to check whether a circuit is live before carrying out further electrical measurements. The DT4221 is specifically designed without resistance and diode testing functions, helping reduce the possibility of accidentally measuring a live circuit while the meter is set to a resistance or diode mode.
The 4-digit LCD provides up to 6000 counts and includes a bar graph for convenient measurement monitoring. The meter is powered by LR03 batteries and provides approximately 40 hours of continuous operation.
For field use, the DT4221 is designed to withstand drops from heights of up to 1 metre. This makes it suitable for electricians, maintenance technicians, and other professionals who require a compact measurement instrument for demanding working environments.
The Hioki DT4221 is part of Hioki's range of professional electrical measurement instruments available through GeneralTech Shop. If you require a model with resistance and diode testing functions, the Hioki DT4222 provides an alternative option.
