Uni-t Ut501b Singal Analyzer. UNI-T UT501B Insulation Resistance TesterCategory: HardwareSubcategory: Measurement ToolsThe Uni-T UT501B Insulation Resistance Tester is a professional-grade diagnostic tool engineered for precision, safety, and reliability. As a vital component of the UT500 series, this device is indispensable for electricians, maintenance engineers, and service technicians who require accurate assessment of electrical insulation. It is expertly designed to ensure the safety and operational integrity of electrical systems by measuring insulation resistance, low resistance, and AC voltage in a wide range of applications, including transformers, motors, cables, switchgear, and other high-voltage installations.This tester provides robust diagnostic capabilities that go beyond simple resistance readings. With the inclusion of advanced functions like Polarization Index (PI) and Dielectric Absorption Ratio (DAR), professionals can perform in-depth analysis of insulation quality over time. These diagnostic tests are crucial for predictive maintenance, helping to identify potential insulation degradation before it leads to equipment failure, thus saving time and costly repairs. The ability to perform continuous measurements allows for stable, long-term monitoring where required.User-centric design is at the core of the UT501B. It features a large, 2000-count LCD display with a bright backlight, ensuring clear and effortless readability even in poorly lit environments. The automatic range selection simplifies operation by eliminating the need for manual adjustments, allowing you to focus on the task at hand. Safety is paramount when working with high-voltage equipment, and the UT501B incorporates a comprehensive alert system. A high-voltage warning light (red LED) and an audible buzzer immediately notify the user of live circuits, significantly enhancing operational safety. Its compact, rugged, and ergonomic design ensures durability for fieldwork while remaining lightweight for easy portability.Main Features:* Selectable Test Voltages: 250V, 500V, 1000V* Advanced Diagnostic Functions: PI (Polarization Index) and DAR (Dielectric Absorption Ratio)* Large 2000-Count LCD Display with Backlight* Automatic Range Selection for Ease of Use* Low Resistance Measurement Capability* AC Voltage Measurement* Continuous Measurement Mode* Data Hold Function* Safety Alert System: High-Voltage Warning LED and Audible Buzzer* Low Battery Indication and Automatic Power Off* Rugged, Drop-Proof ConstructionTechnical Specifications (Testers):* Model: UT501B* Test Voltages: 250V/500V/1000V (0% ~ 10%) * 250V: 0.00MΩ ~ 99.9MΩ ±(3%+5), 100MΩ ~ 5.0GΩ ±(5%+5) * 500V: 0.00MΩ ~ 99.9MΩ ±(3%+5), 100MΩ ~ 5.0GΩ ±(5%+5) * 1000V: 0.00MΩ ~ 99.9MΩ ±(3%+5), 100MΩ ~ 5.5GΩ ±(5%+5)* 50V (R=50kΩ) 1mA (0% ~ 10%) * 100V (R=100kΩ) 1mA (0% ~ 10%) * 250V (R=250kΩ) 1mA (0% ~ 10%) * 500V (R=500kΩ) 1mA (0% ~ 10%) * 1000V (R=1MΩ) 1mA (0% ~ 10%)* Short-Circuit Current: 200mA) ±(2%+3)* AC Voltage (V): 30V ~ 750V ±(2%+3)* Display Count: 2000* Safety Rating: CAT III 600VUni-T UT501B Insulation Resistance Tester.The Uni-T UT501B Insulation Resistance Tester is a versatile and precise measuring device from the UT500 series, designed to measure insulation resistance, AC voltage, and low resistance in electrical installations and equipment.The model offers test voltages of 250V/500V/1000V, measurement accuracy of ±(3%+5), as well as advanced PI and DAR diagnostic functions.Equipped with a clear 2000-count LCD display, automatic range selection, continuous measurement function, and an alert system (buzzer and LED), it ensures convenience and safety when testing transformers, motors, cables, and high-voltage installations.The UT501B stands out for its intuitive operation and compact, rugged design , making it an ideal tool for electricians and service technicians.The model is CE and UKCA certified.Included.Uni-T UT501B Insulation Resistance Tester.Test leads.Alligator clips.Batteries.Carrying strap. tradeinn Bricoinn
