Abstract
The temperature history of a product is visually displayed as a color front on an indicator, the distance of front advancement being a function of the temperature time integral. The indicator measures the gas generation in a first compartment by a wick in a second compartment, the wick also being in communication with the first compartment. Optionally, a gas permeable film separates the gas generating material and the wick.
