Uni-T UT221 Digital Current Meter

Uni-T UT221 Digital Clamp Meter

The Uni-T UT221 is a more advanced clamp meter from the UT220 series, designed to measure high AC and DC currents up to 2000 A. The device was created for professional applications where greater precision, a wider range of functions, and convenient operation are essential when measuring high current values. With a jaw opening of 63 mm, automatic range switching, and a higher maximum reading, this model performs well in more demanding tasks.

Greater capabilities and a wider range of functions

The UT221 model allows for the measurement of AC and DC current up to 2000 A, AC voltage up to 750 V, DC voltage up to 1000 V, resistance up to 66 MΩ, and frequency up to 20 MHz. Compared to the UT220 model, it offers a maximum reading of 6000, True RMS for AC voltage and current, duty cycle measurement, low-pass filter, inrush current measurement, relative mode, and MIN/I-OUT functions. An additional advantage is the 66-segment analog bar graph, which makes it easier to observe changes during measurement.

Ready for more demanding tasks

The meter is equipped with a diode test, continuity buzzer, Data Hold and MAX functions, a full set of icons, and a low battery indicator. Powered by a 9V 6F22 battery, weighing 726 g, and measuring 298 × 107 × 47 mm, this model remains a robust tool for advanced applications.
