Wide Ranging Electro-chemical Based Time-Temperature Recorder

Reference#: P02490


Storage temperature conditions can compromise the quality and performance of many items such as rocket propellants, explosives, medications, frozen foods, various chemical supplies, etc. These products have a long storage life at low temperatures and a much shorter life at higher temperatures. In practice, the storing temperature may not be constant, thus knowing the integral of time and temperature would better help estimate the remaining useful life of the product.

Researchers at the Johns Hopkins Applied Physics Laboratory have developed a wide ranging electro-chemical based, time-temperature recorder that can record how long an object has been subjected to a high temperature and at what temperature it reached.

Some products do not become unusable when temperature is exceeded but their usefulness is diminished. This sensor is simple enough that an unskilled operator can read a simple line on an indicator.
