Uni-T Isolation Resistance Tester Earth Meter Megohmmeter Voltmeter

The UNI-TREND UT502A is a professional insulation resistance tester and earth resistance meter for electrical testing applications. This multifunctional measuring device combines insulation resistance measurement, earth resistance measurement, and AC voltage measurement in a compact unit. With a clear LCD display featuring a backlight for better visibility in low light conditions, the device offers a 2000-count display for precise measurement values. The UT502A insulation resistance tester allows reliable measurements up to 2000 MΩ and is suitable for assessing insulation integrity in motors, transformers, cables, and other electrical installations. The earth resistance measurement function enables accurate testing of grounding systems with a measurement range of up to 2000 Ω. Additionally, the integrated AC voltage meter allows voltage measurements up to 600 V AC. The device includes advanced safety features such as automatic discharge of capacitive voltage and overload protection circuits. The UT502A operates with a standard 8x1.5 V AA battery configuration and comes with test leads, crocodile clips, and auxiliary grounding spikes for comprehensive testing options. With a robust design and an IP54-rated housing, the measuring device is built for demanding field applications and ensures measurement accuracy. The device measures approximately 200 mm x 100 mm x 50 mm and weighs about 800 g without batteries. As a successor to earlier UT series insulation testers, the UT502A maintains the reliability and precision of UNI-TREND professional testing equipment while offering improved display visibility and measurement stability. It is suitable for electricians, maintenance technicians, and electrical engineers in industrial, commercial, and private electrical installations.
