Inhouse product
Elevate your electronics repair and diagnostics workflow with the KOGEEK MESR-100 Pro ESR Meter, a high-precision tool designed for fast, accurate measurement of Equivalent Series Resistance (ESR) and internal resistance in capacitors. Whether you're troubleshooting PCBs, evaluating capacitor health, or performing component-level diagnostics, the MESR-100 offers unmatched convenience, accuracy, and efficiency for DIY enthusiasts, professional technicians, and electronics labs.
Built with advanced measuring algorithms and auto-ranging technology, the MESR-100 allows you to identify faulty capacitors without desoldering, saving time and reducing the risk of damaging sensitive components. It comes equipped with a professional-grade SMD test clip for precise, hands-free measurement on small surface-mount devices and densely packed circuit boards.
Measure ESR values in micro-ohms to ohms range with industry-leading accuracy. Ideal for checking capacitor health in power supplies, TVs, monitors, and industrial boards.
The MESR-100 enables in-circuit testing, letting you measure capacitors without removing them from the PCB – dramatically speeding up diagnostics and repair.
Features a wide dynamic range with auto-scaling, plus a bright backlit LCD screen that clearly displays resistance values and test mode – perfect for low-light environments.
Delivers fast, real-time ESR readings using a 100kHz sine wave signal, ensuring compatibility with both electrolytic and solid-state capacitors.
Equipped with a professional SMD tweezer-style clip for easy and precise testing of tiny surface-mount components on crowded circuit boards.
Lightweight and battery-powered with intuitive controls, the MESR-100 is ideal for use at the bench or in the field.
