sure there is, most of it was done using 1 mhz how ever.
but most of that equipment will drop to lower freqs .
you need something like a capacitive bridge that has
a Q option on it.

I think that Bob Parker's one is mostly useful for values > 1uF, so I
would
be suspicious of using it for film caps unless it is a very big film cap.
It is however very good for testing electrolytics.

I use Bob's meter and consider it an essential part of my tool kit.
Nevertheless it is good to know the limitations of your test
equipment. AFAICS, Bob Parker's ESR meter should read 8 ohms for
a perfect 1uF cap (it actually shows much less than this). Here is my
reasoning:
