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

I bought one meter for current work I’m doing. Since the meter was new to me, I questioned the validity of the measurement. I ordered another to compare the results against once another. The measurements were almost identical. The ESR reading were the same. Unless they all are manufactured with an inaccurate offset, the odds of both meters reading close to identical tells me the meters are accurate. I’m keeping both meters. I measured the same two capacitors 470 uf 50V +/- 20% tolerances with both meters and the data was practically the same. Meter 1: Cap 1 : 415uf ESR .19 Cap 2: 428uf ESR .17 Meter 2: Cap 1: 416 uf ESR .19 Cap 2: 428 uf ESR .17

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.

This thing was a good buy for testing esr..

It does the job and looks and feels nice.

Fabulous meter because it has such a huge range BUT it only tests capacitors at low voltage. Therefore, be aware that the test may not be completely accurate for testing the integrity of high voltage capacitors.

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.

Didn't know what to expect from such an inexpensive meter (professional C meters run from the high $100's to $1000's). Leads are short, but they are banana and you can use longer leads and calibrate for them, nice touch. Highly recommend for the $, if you are not in a research laboratory environment that requires MIL-Spec calibration.

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

This product seems to be made with passion. and it's quite accurate.

Top Capacitor Tester!!!
