The UNI-T UT500 Series Insulation Resistance Testers are designed for electrical professionals and technicians who require precise, safe, and dependable insulation testing. With a clear 2000-count LCD display featuring backlight and overload indication, these testers provide easy-to-read measurements and enhanced safety during operation.
In addition, the auto discharge function safely dissipates residual charges after each test, ensuring the protection of both the user and the equipment. Moreover, the continuous low resistance measurement mode and low resistance returning to zero function improve measurement accuracy, while the built-in red warning light and buzzer provide a clear alert during ongoing measurements.
Furthermore, the UT500 Series supports advanced diagnostics, including Polarization Index (PI) and Dielectric Absorption Ratio (DAR) tests, and can automatically calculate resistivity for a comprehensive analysis. Additionally, these testers are capable of AC voltage measurement and include an auto power-off feature to conserve battery life, making them convenient for extended use in the field.
As a result, the UNI-T UT500 Series Insulation Resistance Testers combine accuracy, advanced functionality, and safety, making them an indispensable tool for professional insulation testing and electrical diagnostics.
