Abstract

A method and apparatus for calibrating the temperature/color correspondence of thermal paint. A strip of metal is heated at both ends independently to achieve a predetermined temperature differential measured by thermocouples. Heat flow from the hot end to the cooler end is constrained to the test piece by enclosing it in insulation material. A linear temperature gradient is thus achieved so providing a more accurate and flexible calibrating arrangement.
