Aye laddie, I do indeed.
There were densitometers and sensitometers, the latter for film,
former for paper. Basically they were for reading test strips to
control processes. Useless in all but large volume labs.
Yeah, I'm aware of what they're used for, although I've always referred
to them as transmission and reflection densitometers (film and paper
respectively).
Although I've used a transmission densitometer on quite a number of
occasions, especially whilst trying out new developers and development
processes. And I'm not exactly a high volume lab -- even the music is
at a low volume these days.
Made for many years in many models at several price ranges, all of
which were high.
And I've read something recently (thanks Karl) suggesting that the olde
vacuum tube densitometers still have a lot of life in them.
I am curious -- and it's just an idle curiosity -- as to what these were
once priced at when new. I can't imagine they were cheap :-)
