Uni-T Insulation resistance tester UT505B

The Uni-T UT505B insulation resistance tester is a professional testing device specifically designed for measuring insulation resistance in electrical systems and components. With five selectable test voltages ranging from 50V to 1000V and a test current of 1mA, this compact device is versatile enough for use in low-voltage circuits as well as high-voltage equipment. The automatic shut-off feature helps extend battery life, while the clear LCD display with backlighting ensures excellent visibility even in low-light conditions. Safety features such as audible and visual warnings when test voltage is present enhance safety during operation. Additionally, the ability to store up to 99 measurement data groups allows for convenient recording and comparison of test results over extended periods. The robust housing and portable design make the UT505B ideal for field use, particularly for electricians, maintenance technicians, and quality control professionals who require reliable insulation measurements.
