Clamp for measuring leakage current UNI-T UT251C+

Product detailed description

This product is covered by a 3-year warranty.

The UT251C+ tick meter is designed to measure AC leakage current. The high-resolution meter is well suited for applications such as checking leakage current of motors, household appliances and other electrical equipment up to 60 A.
It is characterized by 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 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, under-voltage indication, backlight, auto shut-off and more.
UT251C+ has the ability to test or monitor the leakage current of the grounding conductor/system and detect the current of the power distribution box, the current of the small and medium-sized industrial control system, as well as the amplitude, frequency and harmonics of the current of the small/medium-sized equipment or circuit, thus providing the basis 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 of double insulation, CAT III 600V overvoltage and pollution degree 2.
