Thermax is a thermal thermometer paper that uses clear, heat-resistant cellophane to seal a series of temperature grids. When the rated temperature is exceeded, the temperature grid is visibly discolored, providing the historical temperature of the monitored surface. The label does not delaminate when removed for reference and can be attached to the inspection report as a permanent record.
