Sargent Recording pH Stat

This is an old "Recording pH Stat" that my cousin rescued from the trash at his work. He was only interested in the indicator lights, and let me have the rest. I collect old scientific equipment, so i was more than happy to have it!

The only problem, was that it weighed around 80-100lbs. The steel shelves on which my collection resides couldn't hope to support that much mass, so i gutted it. From the outside, it still looks 100% intact, but weighs in at only(?) 30-40lbs. I took these photos as i took it apart, for documentation and "look how cool this is" purposes.

I haven't had any luck in finding information on this device, so please let me know if you have any!
