Thermex can be used to test and monitor heated contacting surfaces from 200 to 300°F (93 to 149°C), alone or in conjunction with pressure- indicating film. Upon exposure to heat, the thin film changes color instantaneously and permanently to reveal temperature distribution between any two contacting surfaces. The intensity of this color change directly relates to the temperature to which it was exposed. This allows users to find high or low temperature zones and minute surface variations.
