Their meter is now broken and they asked me to repair or find another.
The broken one was manufactured by Chemet Products of San Francisco.
That company seems to no longer exist.

So, does anyone know of a similar meter. I don't even know how to search
on Google for such a device. Mainly I don't know what to call it.
