Vintage BECKMAN pH Meter Model G. This instrument was designed in 1936 by Dr. Arnold Beckman, the founder of the Beckman Instruments Company (now Beckman-Coulter). The device was revolutionary because it was the first to combine the whole apparatus (amplifier, electrochemical cell, electrode, calibration dials, batteries, and measuring gauge) into one unit.
Click on image to view larger version The pH meter Model G is contained in a wooden box with the dimensions (in inches): 11.3 (width) x 8.5 (depth) x 11 (height). Weight (without batteries) 13 pounds. 
Click on image to view larger version Outside of the scientific community the Model G pH meter has become famous as a prop in the movie Ghostbusters. See the discussion at this web site. 
Click on image to view larger version Nearly all Model G pH meters show major signs of use due to their age and the corrosive action of the liquids that were investigated. In contrast, the present meter is in good condition with smooth wood surfaces (exception: there is a small defect in the veneer in the rear of the top cover) and shiny metal parts. All controls move easily. The meter looks like it has been refurbished. The meter comes with the instruction sheet which has substantial water damage. Also included is a 50 milli-liter Pyrex glass container.
