MF470 Capacitor Tester, ESR Meter Microfarad Meter Farad Super Capacitor Tester, Auto Ranging Capacitor Meter, Electrical Meter Measurement 0.01pF to 470,000,000uF

This works surprisingly well for me, and the battery has never died on me. Extremely easy to use and you can even use multimeter leads. Small and compact with a bright screen that you can see over the LEDS in your workspace.

I needed something that would measure larger capacitors and ESR is a bonus. Works beautifully. Would not hesitate to recommend.

Seems to be pretty accurate and a good value.

I used this device to help me repair a car stereo with a bad cd changer input(that I use as an aux port). I fully disassembled it down to the circuit board and found a bunch of capacitors had leaked onto the board. Thankfully it had not been long and the corrosion was minimal. I tested all the caps on the board, but only 70% of them could be tested directly on the board (meaning "in-circuit"). The rest had to be removed from the board to be tested. Looking at it one way it saved me a lot of time testing if I'd had to unsolder them all. On the other hand, my expectation was that it could properly test in-circuit so it ended up taking way longer than I had expected. In the end I replaced all the bad caps and the cd-changer input works correctly again. It was cheap enough to be useful for a hobbyist, but I'd think long and hard about buying it again versus a better unit that can test in-circuit. We are talking hours longer for diagnosis, and you'd better have replacement caps on hand if you screw any up desoldering them.

Excelente, igual a la descripción

It’s a god tester, useful
