Abstract
A temperature measuring device engageable with a surface of any contour to determine the individual temperature of each of the several portions of the surface by providing a thermal map. The map is observable and may be photographed if a record thereof is desired. The temperature measuring device has a portion engageable with the surface and conformable to the surface. The portion which engages the surface includes a coating of cholesteric material, such as microencapsulated liquid crystal material which is temperature-sensitive and light-reflecting. The device also includes a transparent fill material therewithin to transmit the thermal image or map therethrough. Thus, a thermal map or image of the surface is provided. The thermal map is observable and/or recordable through another portion of the device.
