The Vacuum Regulator, 100-Watts, is a solid state mercury-free digital regulator and designed for precise measurement and control for a range of laboratory vacuum applications. It is preset to control at 300mm below atmospheric pressure as needed for viscous asphalt testing with Asphalt Institute, Cannon-Manning, and Modified Koppers vacuum viscometers, but may also be user reset to control anywhere in the range from 1-410mm below atmospheric pressure. An LCD screen displays vacuum in mm Hg or any of nine other units. The vertical configuration is designed for convenient display and keypad access while minimal counter space is used.
This model is for regulation of user’s existing vacuum system. Also has housing of enameled steel supported with rubber feet.
