Insulation Resistance Tester Model UT505A

Uni-T UT505A Insulation Resistance Tester The Uni-T UT505A insulation resistance tester is an advanced tool designed for precise measurement of insulation resistance and other electrical parameters in various applications. Its extensive features and high accuracy make the UT505A ideal for electricians, service technicians, and engineers. Precise Insulation Resistance Measurements The UT505A offers a wide range of insulation resistance measurements at various test voltages, from 50 V to 1000 V. The device measures resistance from 0.01 MΩ to 20 GΩ, with an accuracy of ±(1.5%+5) for higher voltage values, allowing for accurate diagnosis of insulation condition under various conditions. A test current of 1 mA and low short-circuit current (<2 mA) guarantee safe and reliable measurements. Versatile Measurement Functions The UT505A has additional measurement ranges, such as low resistance measurement (from 0.01 Ω to 20 kΩ), DC and AC voltage up to 600 V, making it a versatile tool for comprehensive analysis of electrical circuits. Functions such as polarization index and dielectric absorption (60 s/15 s, 60 s/30 s) enable advanced diagnostic tests, particularly useful in assessing the condition of insulation in various materials. User-Friendly Functions and Ease of Use The UT505A features automatic range selection, True RMS, a timer, and automatic discharge of the test charge, increasing user convenience and safety. Additional features such as an analog bar graph, last reading hold, data logging (up to 99 results), and a comparative function enable efficient work and analysis of results. The backlit LCD screen with a maximum reading of 6000 ensures readability in various lighting conditions. Robust Construction and Portability The UT505A is compact (103 x 225 x 59 mm) and lightweight (630 g), making it easy to carry and convenient to use on-site. The device is powered by six 1.5 V (LR6) batteries, providing long operating time. The kit includes essential accessories such as test leads, test clips, and a carrying case, facilitating storage and transport.
