UNI T Insulation Resistance Tester UT501A is used to measure the insulation resistance of electrical equipment and household appliances. This UT-501A earth insulation resistance meter is done by measuring the insulation resistance between electrical circuits or between circuits and the ground. This megohmmeter voltmeter can measure insulation resistance, AC Voltage, low resistance, PI (Polarization Index), and DAR (Dielectric Absorption). This insulation megger ideal tools for ensuring transformers, generators, high voltage motors, power capacitors, power cables, arresters, and other electrical equipment that can operate in a safe and accurate manner. 

Features:

• Measure insulation resistance across a wide range
• Test voltages of 100V, 250V, 500V, and 1000V
• Large size LCD screen with backlight (can be switched on/off)
• 2000 count display
• Simple-to-use
• Large test initiate button
• Ports for test leads
• Data hold function
• Various indicators available on the device
