Thermochron® loggers are small and light enough to record changes of temperature quickly. However, they are not waterproof and will not withstand the pressures inside sterilizers or autoclaves. A number of capsules are available to protect these loggers against liquids and high pressure conditions. However, a protective capsule may slow the response of the logger to sudden changes in temperature.
This test was conducted to determine the thermal performance of two types of protective capsule during a sudden extreme change in temperature.
