The Uni-T UT533 is a practical 2-in-1 instrument that combines a True RMS digital multimeter and an insulation tester up to 1000 V. It enables accurate measurement of voltage, current, resistance, capacitance, and temperature, while also reliably verifying the insulation condition of cables, motors, and electrical installations in both home and professional environments.
The Uni-T UT533 insulation resistance tester is a versatile solution for electricians, maintenance teams, and laboratory measurements. Thanks to the combination of a multimeter and a megohmmeter, it saves time and space in your tool bag and allows quick switching between standard electrical measurements and insulation testing.
The True RMS function ensures more accurate results even with distorted waveforms commonly found in modern installations. A large backlit display with 5999-count resolution and dual display makes reading and comparing values easier.
