The UNI-T UT222 is a True RMS AC/DC clamp meter designed for measuring currents up to 2500A through its large 63mm jaw. It combines high-current measurement with voltage, resistance, capacitance, frequency and temperature functions for industrial electrical testing and maintenance.
Key Features
- Measures AC and DC current up to 2500A through a 63mm jaw
- True RMS measurement for improved accuracy on non-sinusoidal signals
- Measures AC/DC voltage, resistance, capacitance, frequency and temperature
- Inrush-current and low-pass filter functions for industrial equipment testing
- Stores up to 1000 readings for measurement review and documentation
