It looks like a bridge with a standard cell. A posh volt meter tester from old times.

The Plexiglass bit with a motor on it looks like it's part of some sort of sampling setup: it doesn't look like it was part of the original instrument.

Could it be some sort of pH-measuring device?

The 'buffer solution' would generally refer to something of a known pH (acidity/alkalinity) an would be used to calibrate a pH meter. So I think G6Tanuki's suggestion is correct.
