Abstract
Abstract The finding of the average temperature of a body or space over a period of time in which a device having two electrodes immersed in an electrolytic bath is placed in the body or space and a current is passed from one electrode to the other for the time period for which it is desired to know the average temperature. The amount of metal transferred between the electrodes during such time period is determined and the average temperature during the time from the known relationship between the amount of metal transferred, the electrolytic bath, the length of time over which the current passes from one electrode to the other and the impressed e.m.f. is calculated.

Claim 1
Independent Claim
208 words
A device for use in ascertaining the average temperature of a body or space over a period of time, comprising a hollow tubular body of transparent plastic material, said body having open ends, an electrode closing each open end and extending within the body with the electrodes being arranged in axially spaced relationship, a plug mounted within the tubular body between the electrodes, said plug having passageways extending therethrough, the cross-sectional area of the passageways determining the life of the device in use, each end of the plug being provided with a depression and a cavity defining gas bubble traps, an electrolytic bath within said body within which at least a part of each electrode is immersed for depositing or removing metal on or from at least one of the electrodes upon the passage of a current from one electrode to the other electrode through the bath, and means operably related with said electrodes for passing an electric current to the electrodes for a time period during which it is required to know the average temperature in which the device operates whereby the transfer of metal between the electrodes gives an indication of the average temperature which is operated for the time during which the current has passed.
