For sale is a vintage 1930's Beckman PH Meter. This is the original model design from when it was invented in the 1930's and is the same exact, accurate style box used in Ghostbusters during Venkmans classic ESP test scene.There werent many like this one made and the designs of the Beckman PH Meters constantly changed. This piece is an antique and EXTREMELY RARE. This is the one and only movie accurate PH Meter I have seen since i identified it as being the shock box used in the movie years ago on therpf. The only other one I have ever seen was in the movie itself.
It was slightly modified in the movie. If you want to make it more accurate, go for it! One of the round knobs is damaged but can easily be replaced with a similar common mil-spec knob.
