The TELEVAC MC 300 vacuum instrument utilizes the patented sensor technology with advanced electronics for reliable, flexible measurement and control. It can measure vacuum ranges from ambient atmosphere down to 10-10 Torr. Sensors include thermocouple, cold cathode, and convection for a wide range of applications. The series also features a bright LED display; built-in self diagnostics; selectable units in Torr, microns, mBar or Pascal; gas compensation, Argon N2; four process relays with individually assignable set points; recorder outputs for each sensor; operator lockout switch, and optional digital communication interface.
