LCR meter
Handheld LCR meter · test signal 0.5 V at 1 kHz through 100 Ω · reads R, L, C and ESR of the part between its clips · measure parts out of circuit, power off

Try it on the benchThe lab drops it on an empty bench and opens its datasheet card.

How to use it
Out-of-circuit component checks: a bulging electrolytic shows high ESR long before its capacitance drops.
