Overview
The UAT-D UT31 is a versatile 3.5-digit handheld digital multimeter designed for precision, safety, and ease of use. Unlike basic “yellow” meters, the UT31 comes equipped with a double-fuse protection system, making it significantly more reliable for classroom and home use. Whether you are measuring battery voltages, checking circuit continuity with the loud integrated buzzer, or testing the temperature of a 3D printer nozzle, the UT31 provides clear, stable readings on its large LCD.
Key Features
All-in-One Utility: Measures Voltage (AC/DC), Current (DC), Resistance, Capacitance, and Temperature.
Troubleshooting Hero: Includes a built-in Continuity Buzzer for rapid circuit testing without looking at the screen.
Safety First: Features double-fuse overload protection to prevent damage during accidental mis-wiring.
Component Testing: Integrated Diode and Transistor (hFE) test functions for identifying faulty components.
Beginner Friendly: Clear 1999-count LCD display with a low-battery indicator and sharp, high-quality test probes.
