Abstract: The thaw indicator is a device to determine if a frozen space has gone thru an undesired temperature change and if so remains in an alert position until manually reset even if the temperature corrects itself. It's made up of three major components a base, a piston indicator and a transparent tube. When frozen the thaw indicator looks like a thermometer when unfrozen it looks like a thermometer that has jumped out of its case indicating a change of temperature and state with great certainty. It has been designed to stay out of the way but in plain sight.
