UT512 Insulation Resistance Tester

UT512 Insulation Resistance Tester

Uni-T UT512 Insulation Resistance Tester The Uni-T UT512 Insulation Resistance Tester is a professional measuring tool designed for precise testing of insulation condition across a wide range of test voltages. With advanced features and high accuracy, the UT512 is ideal for electricians, engineers, and technicians involved in the maintenance and diagnostics of electrical installations. Precise Insulation Resistance Measurements The UT512 allows for insulation resistance measurement at four different test voltages: 500 V, 1000 V, 1500 V, and 2500 V. Measurement ranges are from 0.5 MΩ to 100 GΩ, with accuracy up to ±(3%+5) for the 100 kΩ ~ 10 MΩ range, allowing for accurate assessment of insulation condition. A test current of 1 ~ 1.2 mA and low short-circuit current (<2 mA) ensure safe and stable measurements. Versatile Diagnostic Functions The UT512 offers additional functions for measuring DC and AC voltage in the range of 30 V to 600 V, with accuracy of ±(2%+5), making it a versatile tool for electrical diagnostics. The device also features dielectric absorption and polarization index functions, which allow for a deeper analysis of insulation properties, crucial in preventing failures and ensuring the safety of installations. Intuitive Operation and Ergonomics The UT512 features a backlit LCD screen measuring 123 x 58 mm, ensuring readability in various lighting conditions. Automatic ranging, an analog bar graph, and a comparative function simplify operation and speed up the measurement process. The meter has memory for 18 measurement records, allowing for easy storage and analysis of results. Durable Construction and User Convenience The UT512 is powered by eight 1.5 V (LR14) batteries and has an auto-power-off function, saving energy and extending battery life. Its robust construction with dimensions of 202 x 155 x 94 mm and a weight of 1.8 kg makes the device durable and resistant to daily use. The set includes special test leads with crocodile clips, a USB cable, an external power supply, and a carrying case for easy storage and transport.
