Abstract

A device for monitoring temperature conditions in a frozen food storage space includes a rear panel and a parallel transparent plastic front wall having a peripheral skirt wall sealed to the panel front face. Laterally spaced projections intermediate the front wall top and bottom extend from the front toward the rear wall to delineate top and bottom cavity sections, one of which contains colored water. A suction cup is located on the panel rear face and indicia are formed on the panel front face registering with each cavity section. The device is located in the storage space until the water in the lower cavity section is frozen solid and is then inverted. The presence of water in the bottom cavity of the inverted device indicates the occurrence of a thawing condition in the storage space at the same time.
