Your typical ph meter (empty casing)

Here is the backside of the board... red arrow points at the calibration screw.

This is the front of the board... switch to turn on, electrode.. and I don't know what the purpose of the other wire is. I'm assuming it adjusts temperature to compensate readings properly.
