UNI-T UT251C+ Leakage Current Measuring Clamp

This product comes with a 3-year warranty.

The UT251C+ clamp meter is designed to measure AC leakage current. The high resolution meter is great for applications such as checking the leakage current of motors, household appliances and other electrical equipment up to 60A.
It features features such as high reliability, high safety, full range overload protection and unique appearance. As a practical measuring instrument for electricians, the UT251C+ can be used to measure AC leakage current at the uA level, current below 60 A, frequency and harmonic frequencies. This clamp meter is designed with multiple features including data storage, low pass filter, Bluetooth communication, undervoltage indication, backlight, auto shut-off and more.
The UT251C+ has the ability to test or monitor ground wire/system leakage current and detect distribution box current, small and medium industrial control system current, as well as small/medium equipment or circuit current amplitude, frequency and harmonics, providing the foundation for power quality analysis.

The meter is designed in accordance with IEC/EN61010-1, 61010-2-032 and electromagnetic radiation protection according to EN61326-1 and meets the requirements for double insulation, CAT III 600V overvoltage and pollution degree 2
