The Signtek ESR meter is a popular choice on this list, as it promises and delivers excellent craftsmanship and performance. This ESR meter measures an accurate value of ESR by using a true 100 kHz sine wave which completely removes the impedance which is almost the same as the testing method of a capacitor manufacturer. Using this exact method, this little device can check the condition of the capacitor. And because this ESR meter applies less than 15mV or peak to peak on a good capacitor, we can also use it as a circuit test. The low voltage gives you a huge benefit as while you’re testing something out, the semiconductor will not turn automatically on inside a circuit. So while you’re repairing a TV, LCD, or audio board, you can do in-circuit testing without the entire de-soldering process.

6. BSIDE ESR Meter
