Maximum temperature indicator |
摘要 |
A maximum temperature indicator comprises a body of inexpensive and highly durable polymeric material adapted to be affixed to a support, such as within a mechanical device. The polymeric material undergoes a detectable physical change unique to a maximum temperature to which the polymeric material was exposed. After exposure, the polymeric material is easily tested to accurately determine the maximum temperature that the sample was exposed to.
