Applications
McPherson is a Massachusetts-based scientific instruments company best known for spectrometers and vacuum ultraviolet (VUV) optical instruments. The Model 815 Pumping Control System was used in laboratory vacuum system setups — typically to automate and monitor the sequential operation of roughing pumps, turbomolecular pumps, or diffusion pumps used to evacuate optical instrument chambers and vacuum deposition systems. These controllers were common on McPherson spectrometer systems and related optical bench setups from the 1970s and 1980s, where maintaining and monitoring vacuum levels was critical to instrument performance. Buyers today are typically researchers, universities, or labs maintaining legacy McPherson optical instruments and spectrometers, or those seeking parts for similar vintage vacuum control panels.
This McPherson 815 Pumping Control System is being sold AS-IS for parts or repair. The glass on the center panel gauge is broken, as clearly visible in the photos. The unit has not been tested and no functionality is guaranteed. It may be suitable for parts harvesting or restoration. Please view our photo set and contact us if you have any questions.
