UNI-T UT139A True RMS Digital Multimeter

The UNI-T UT139A True RMS model is a top choice for electricians seeking a reliable and versatile digital multimeter. With its advanced features and True RMS capabilities, this multimeter is designed to meet the demands of professional electricians and DIY enthusiasts alike. In this article, we will explore the key attributes of the UT139A and understand why it stands out as a go-to tool for accurate electrical measurements.

Precision and Accuracy

The UT139A offers True RMS measurements, ensuring accurate readings of both sinusoidal and non-sinusoidal waveforms. This feature is essential when dealing with complex electrical systems, making it suitable for troubleshooting and advanced applications.

NCV and LoZ Functions

The multimeter comes equipped with NCV (Non-Contact Voltage) detection, providing a safer and more convenient way to detect live electrical circuits. Additionally, the UT139A has a special model with LoZ (Low Impedance) functionality, enabling the measurement of ‘ghost’ voltages. These features are invaluable for electricians working in diverse environments.

Analog Bargraph and LED Backlight

The UT139A features a 31-segment analog bar graph, allowing users to visualize changes in readings quickly. The built-in LED backlight enhances visibility, making it easier to use the multimeter in dimly lit areas or during nighttime tasks.

Diverse Measurement Options

With the UT139A, electricians can measure AC/DC voltage, AC/DC current, resistance, capacitance, frequency, and temperature, and perform continuity and diode tests. The auto and manual range selection provides added flexibility based on the specific measurement requirements.
