Title: Photoelectric Colorimeter, Photoelectric Colorimeter

Creator: Rittase, William M.
Dates: 1937
Resource: ExxonMobil historical collection
Description: A black and white photo of a man working on a machine called the photoelectric colorimeter. On the back of the photo, there’s an inscription that reads, "11. Photoelectric Colorimeter, While the color of an oil is not usually significant in itself, color may become very important in conjunction with other considerations. Uniformity of processing or the relative behavior of oils under certain conditions are examples of a need for precise color measurement. Most of the methods for measuring color involve the human eye to a greater or less degree but the human eye is often incapable of good precision and varies considerably from one time to another and among different individuals. In this colorimeter developed by the Research and Development Laboratories the human equation has been eliminated, hence it yields greater precision than is possible by visual methods of color measurement. (Research and Development Division)" There’s a stamp that reads, "Photo by, William M. Rittase, 247 S. 15th St., Phila Pa, Phone, Pen 1418, Print No. S.V. 20 1937."
