UT501B Insulation Resistance Tester

UT501B Insulation Resistance Meter The UT501B insulation resistance meter is a professional tool for measuring insulation resistance in electrical installations and devices. Its advanced features and wide measurement ranges make it ideal for electricians and technicians involved in the diagnostics and maintenance of electrical systems. UT501B allows for insulation resistance measurements at three test voltage levels: 250 V, 500 V, and 1000 V, with a measurement range up to 5 GOhm. With high accuracy of ±(3%+5) for the 0 ~ 99.9 MOhm range and ±(5%+5) for the 100 MOhm ~ 5 GOhm range, the device provides precise results under various test conditions. The UT501B features automatic range selection, dielectric absorption testing, and polarization index, allowing for quick and accurate measurements. Additionally, the device has a low battery indicator, a high voltage warning, and a backlit LCD screen, increasing safety and user comfort. The UT501B is characterized by its compact dimensions (150 x 100 x 71 mm) and low weight (0.5 kg), making it easy to transport and use. The meter is powered by six 1.5 V (LR6) batteries, which provide long life. The set includes all necessary accessories, such as test leads, alligator clips, and a case, allowing for immediate commencement of work.
