UNI-T UT502 Insulation Resistance Tester “Megger”
The UNI-T UT502 Insulation Resistance Tester “Megger” is a professional digital insulation testing device designed for accurate insulation resistance measurement in electrical systems, industrial equipment, transformers, motors, generators, cables, and power installations. Built for electricians, maintenance engineers, and industrial technicians, the UT502 delivers reliable high-voltage insulation testing with selectable test voltages up to 2500V and insulation resistance measurement up to 20GΩ.
Equipped with advanced diagnostic functions such as Polarization Index (PI) and Dielectric Absorption Ratio (DAR), the UT502 helps evaluate insulation condition and detect early insulation deterioration. Its rugged industrial design, backlit LCD display, audible and visual alarms, and automatic discharge protection make it ideal for professional maintenance and inspection applications.
