Abstract
Abstract A device for accurately measuring the temperature of a laminator and the method of using this device. This device is made from a cylindrical body adapted for tension adjustment, a probe, a means for adjusting tension which is positioned between the probe and the cylindrical body, a thermally conductive body attached to the probe and a thermocouple attached to the conductive metal body. This device is positioned perpendicular to a laminator platen during operation of the laminator. The temperature may be read from an appropriate meter to which the thermocouple of the device is attached.
