The High Precision Milliohm Meter is a compact and reliable low-resistance and capacitance testing module designed for accurate electrical measurements. With a wide resistance range of 0.001Ω to 120Ω and an impressive 1mΩ resolution, it allows precise testing of PCB traces, battery internal resistance, inductors, and low-value resistors. Additionally, the built-in capacitance measurement function supports values from 10pF to 20000μF, making it a versatile diagnostic tool for electronics repair and development. Because it operates on a simple 7–12V DC supply and consumes less than 100mA, it ensures stable and efficient performance. Whether you are working in a laboratory, service center, or R&D environment, this module delivers fast, accurate, and repeatable results. Featured By RoboticsBD.
