Features:

High Precision ESR Measurement: The MESR-100 ESR Meter is designed for accurate measurement of the Equivalent Series Resistance (ESR) inside capacitors, with a wide range of 0.001 to 100.0Ω. Utilizing a true 100kHz sine wave, it matches the testing methods used by capacitor manufacturers, ensuring you get precise results. The high resolution of 4 digits (0.001Ω @ 1Ω range) offers detailed data, making it ideal for diagnosing capacitor health in various electronics.

In-Circuit Testing Capability: This ESR meter is capable of performing tests in-circuit, thanks to its low testing voltage of less than 15mV DC or peak-to-peak. This allows you to evaluate capacitors directly on the board without needing to remove them, saving time and effort during repairs of TVs, LCDs, audio boards, and other electronic devices. The ability to test components in situ helps maintain circuit integrity while troubleshooting.

Fast and Efficient Analysis: The auto-ranging feature allows for swift and accurate measurements, with refresh times of around 0.4 seconds. The device instantly provides results, reducing the waiting time during diagnostics. This feature, combined with the ESR table printed on the body, enables quick reference and verification of capacitor conditions, making your diagnostic process both efficient and straightforward.

User-Friendly Design: Featuring dual terminals and an included SMD alligator clip, the MESR-100 ensures easy and quick connection to capacitors. The copper-plated surface of the clips is anti-corrosive and oxidation-resistant, ensuring reliability and longevity. The compact dimensions (14.5 x 8 x 3cm and a weight of 139.6g) make it portable and convenient for fieldwork or lab use.

Power Flexibility and Longevity: Powered by either a 5V micro USB connection or 2 AA batteries, the MESR-100 provides flexibility to suit various working environments. The device has a low operating current of 0.02A, contributing to a battery life of over 80 hours. This ensures you can rely on it for extended periods without frequent battery changes or recharges, keeping your workflow uninterrupted.
