Uni-T 502C Insulation Resistance Tester is a professional-grade megohmmeter (megger) designed for testing the insulation integrity of high-voltage equipment, cables, transformers, and motors. It is a critical safety and maintenance tool for electrical engineers and contractors in Uganda who need to verify that electrical insulation is not leaking or degrading, which could lead to short circuits or fires.
With a massive testing voltage range up to 2500V and a measuring capacity of up to 20GΩ, the UT502C is built for heavy-duty industrial and utility-scale diagnostics.
High-Voltage Testing: Offers four selectable test voltages (500V, 1000V, 2500V) to match different equipment ratings.
Massive Resistance Range: Measures insulation resistance up to 20GΩ, allowing for the detection of even the slightest insulation breakdown.
Auto-Calculation of PI and DAR: Automatically calculates the Polarization Index (PI) and Dielectric Absorption Ratio (DAR), providing a deeper analysis of the insulation's health over time.
AC/DC Voltage Measurement: Includes a standard voltmeter function up to 1000V DC and 750V AC for general circuit checking.
Large Backlit LCD: The 2000-count display features a high-contrast backlight, making it easy to read in dark substations or industrial basements.
Auto-Discharge Function: For safety, the device automatically discharges the voltage from the equipment under test once the measurement is finished.
Rugged & Portable: Encased in a durable industrial shell designed to withstand the rigors of field work.
