Corning PH meter

I bought this from NCSU Surplus for $1. I liked the 70's design and the big panel meter (the biggest panel meter I have ever seen.)

The circuit board is very striking, with lots of colorful components. On the inside of the back cover is a schematic of the meter (something which you would never see these days. The main outer case is cast aluminum, with a bent aluminum back cover.

It came from the Entymology department, which I could have guessed from all the dead bugs inside.

My plans are to remove the circuit board and use it as an enclosure for a Chronulator. I plan to use the hour meter to tell the time, since it is large enough.

I figured out how to mount the meter without the circuit board, and built the Chronulator. The main roadblock now is completing the meter face.
