MONITORING OF TEMPERATURE OF REFRIGERATED GOODS AND FROZEN GOODS AND APPARATUS FOR IMPLEMENTING THE SAME

摘要

PURPOSE: To prevent intentional alteration of indication comprehensively by an arrangement by arranging two tracers while shifting such that when at least one indicator is melted the indicator is subjected to gravitation and flows into other hollow part in a cavity. CONSTITUTION: Two single case type tracers 1, 2 are fixed to a cold-storage goods while avoiding common position. Indicators 4, 5 are frozen and when the tracer 1 is turned by 180 deg. at that position, the indicator 4 is located above and the indicator 5 is located below. When the tracer is fixed vertically to the cold-storage goods, the indicator 5 is held as it is even if it is melted but the indicator 4 is melted and flows down to the lower part in the cavity 3. Consequently, the indication can be prevented from being altered by turning down one tracer to cause gravitational flow down.
