B & K Precision Model 881 ESR Meter
This In-circuit ESR & DC Resistance capacitor tester is specially designed to measure ESR (equivalent Series Resistance) on electrolytic capacitors in the range of 0.47uF to 2200uF, in or out of circuit. The ability to trouble shoot in-circuit (onboard) saves time without removing the components from the board. This meter have an output test frequency of 100 khz with a 15mvp-p output test voltage so that it would not turn on any solid state devices, and have the ability to discharge the capacitors when under test. The selling price is US205 and comes with one year warranty.
