Since 1938, Cannon Instrument Company has carried the name of a Penn State research breakthrough into a specialized Central Pennsylvania manufacturing business. Founded by scientist, inventor, and educator Dr. Michael R. Cannon, the company is best known for developing the Cannon-Fenske Routine Viscometer, whose design became the world’s most widely used manual glass viscometer. Today, Cannon serves laboratory customers with testing instruments and related calibration services, supported by ISO 9001:2015 certification and A2LA accreditation.
