Uni-T UT221 digital clamp meter
The Uni-T UT221 is an advanced clamp meter designed to measure high AC and DC currents up to 2000 A. With a large jaw opening of 63 mm and automatic range switching, the device performs well when working with complex electrical and industrial installations. The model allows for measuring AC voltage up to 750 V, DC voltage up to 1000 V, resistance up to 66 MΩ, and frequency up to 20 MHz. Additionally, it offers True RMS for AC voltage and current, duty cycle measurement, a low-pass filter, inrush current measurement, and relative mode, which expands its capabilities when diagnosing more demanding systems.
Convenient operation and features supporting daily work
A maximum reading of 6000 and a 66-segment analog bar graph make it easy to observe changes in measured parameters. The meter is equipped with MIN/I-OUT, Data Hold, MAX, diode test, and continuity buzzer functions, allowing for convenient performance of a variety of measurements. A clear set of icons, a low-battery indicator, and a robust design measuring 298 × 107 × 47 mm and weighing 726 g make the Uni-T UT221 a practical tool for more demanding measurement applications.
