HIOKI DIGITAL MULTIMETER DT4221-20, Premier Pocket DMM with CAT IV 300 V, CAT III 600 V Safety

The DT4221 is a pocket-sized digital multimeter designed specifically for electrical work requiring optimal safety, with ±0.5% DC V accuracy and wide 40 Hz to 1 kHz AC V bandwidth.

- Achieving a high level of safety in a compact body and lightweight design
- Resistance and diode testing functions omitted by design in pursuit of added safety (DT4221)
- Voltage detection function (DT4221)
- Robust design capable of withstanding a drop from a height of 1 m
- ±0.5% DC V basic accuracy, wide 40 Hz to 1 kHz AC V frequency characteristics
- Low-pass filter cuts high harmonics (when measuring inverter fundamental waveforms)
- Broad -10°C to 50°C (14°F to 122°F) operating temperature range
