Product Description
The AUTOOL DM103 is a high-precision digital LCR tweezer designed for efficient and accurate testing of SMD components. It combines the functions of an LCR meter and a tweezer in one compact tool, allowing you to easily measure inductance (L), capacitance (C), and resistance (R), as well as perform diode polarity checks and continuity tests. With its built-in automatic component recognition, the device identifies resistors, capacitors, and inductors instantly and displays key parameters such as D/Q values with ±0.5% accuracy. The HD OLED screen ensures clear readings even in bright or low-light environments, while the rechargeable lithium battery supports up to 12 hours of continuous use. Whether you are troubleshooting circuit boards, inspecting electronic components, or working on DIY electronics projects, the DM103 helps you quickly assess component conditions without the need for bulky equipment. Its fine gold-plated tweezers make it easy to grip tiny SMD parts, improving both efficiency and convenience in daily repair and testing tasks.
