Any new solution?

Not that I'm aware of.
To get a higher sample rate some one could build this circuit using a FPGA to do the sampling.
That would be a very powerful tool to have.

Hello johan,

I'm also interested to buy the same kit as you, could you post a small review of
the instrument, or saying what you think about it ?
How much does it cost also ?
I thank you in advance !

Sorry, I missed your post. Here is the thread about the meter: LRC + ESR meter kit - built

I haven't used it much since I built it, so I haven't used its full capabilities, but sure it is nice to connect a capacitor or inductor/choke of almost any size to the test leads and get a reading. After making short test leads I get very stable readings.

Hello,

Thank you Johan, but i've already bought one on mid December and fully finished it the past weekend.
The ESR meter seem work well and it's a good device on my lab.
Some comparaison with the high-end RLC meter at my job reveal good precision.
Below, some pictures of the boxed RLC meter.
Regards.

Nice build!

What about the MASTECH MS5308 ? anyone tested this meter?

Check out the eevblog forum on equipment review. There is a brief review on that LCR meter recently. Lots of information on equipments at that site.
