Uni Ut511 Insulation Resistance Meter

Uni Ut511 Insulation Resistance Meter Clear . UNI-T UT511 Insulation Resistance Meter | Professional High-Voltage Diagnostic TesterEnsure the safety, reliability, and performance of your high-voltage electrical systems with the UNI-T UT511 Insulation Resistance Meter. This professional-grade instrument is an indispensable tool for electricians, maintenance engineers, and technicians involved in the installation, servicing, and inspection of large transformers, generators, high-voltage motors, power capacitors, and long-distance cabling. Engineered for precision and built for the field, the UT511 provides accurate, repeatable measurements to help you identify potential insulation failures before they lead to costly downtime or hazardous situations.The core benefit of the UT511 lies in its ability to perform comprehensive insulation diagnostics. By applying a stable, high-purity DC voltage, it precisely measures the integrity of electrical insulation, allowing for early detection of degradation caused by moisture, contamination, or aging. Its advanced diagnostic functions, including Polarization Index (PI) and Dielectric Absorption Ratio (DAR), provide deeper insights into the condition of insulation materials, enabling predictive maintenance and confident asset management. The clear, large backlit LCD with an analog bar graph ensures excellent readability in all lighting conditions, from bright sunlight to dark electrical rooms, displaying critical information at a glance. The integrated comparison function streamlines quality control and repetitive testing by allowing you to set a resistance threshold for quick pass/fail analysis, significantly improving workflow efficiency.Main Features* Wide Insulation Resistance Measurement Range up to 10GΩ* Selectable Test Voltages: 100V, 250V, 500V, 1000V* Automatic Calculation of Polarization Index (PI)* Automatic Calculation of Dielectric Absorption Ratio (DAR)* Comparison Function with Pass/Fail Indication for Rapid Sorting* Continuous and Timed Measurement Modes* Accurate AC and DC Voltage Measurement up to 600V* Large Digital LCD with Backlight* 60-Segment Analog Bar Graph for Visualizing Dynamic Changes* Data Logging Capability for up to 18 Readings* Auto Ranging for Seamless Operation* Auto Power-Off to Conserve Battery Life* Low Battery Indication and High Voltage Warning* Robust, Ergonomic Design for Field UseTechnical SpecificationsAttribute: TestersModel: UT511Safety Rating: CAT III 600VInsulation Resistance (Ω)* Test Voltages: 100V / 250V / 500V / 1000V (0% ~ 20%)* 100V Range: 0.1MΩ ~ 500MΩ, Accuracy: ±(3%+5)* 250V Range: 0.4MΩ ~ 2GΩ, Accuracy: ±(3%+5)* 500V Range: 1MΩ ~ 4GΩ, Accuracy: ±(3%+5)* 1000V Range: 2MΩ ~ 10GΩ, Accuracy: ±(3%+5)* Short-circuit Current: . tradeinn Bricoinn
