The Story
The UNI-T UT501B is a professional insulation tester designed for measuring insulation resistance of electrical equipment and household appliances. It supports test voltages of 100V, 250V, 500V, and 1000V, and measures insulation resistance up to 5GΩ. Additionally, it can measure AC voltage, low resistance, polarization index (PI), and dielectric absorption ratio (DAR), making it ideal for ensuring the safety and accuracy of transformers, generators, motors, and cables.
