A system and method for controlling a temperature indicator stick includes a housing having an interior configured to receive the temperature indicator stick configured to indicate a predetermined temperature through a physical change or a chemical when exposed to the predetermined temperature. A gear is supported by the housing that extends from beyond an exterior of the housing into the interior of the housing to engage the temperature indicator stick. Accordingly, rotation of the gear from the exterior causes a retraction or advancement of the temperature indicator stick to and from the interior of the housing.

System and method for controlling temperature indicators

A system and method for controlling a temperature indicator stick includes a housing having an interior configured to receive the temperature indicator stick configured to indicate a predetermined temperature through a physical change or a chemical when exposed to the predetermined temperature. A roller drive is supported by the housing to engage the temperature indicator stick. Accordingly, rotation of the drive roller causes a retraction or advancement of the temperature indicator stick to and from the interior of the housing. Additionally, the housing and temperature indicator stick may include a key system to keep the temperature indicator stick in a substantially fixed rotational position with respect to the housing as the temperature indicator stick advanced from and retracted into the housing.

A system and method for a multi-temperature indicator stick. The multi-temperature indicator stick includes an elongated stick configured to indicate two or more predetermined temperatures. The elongated stick includes a first temperature indication material configured to indicate a first predetermined temperature upon being subjected to the first predetermined temperature. The elongated stick also includes a second temperature indication material configured to indicate a second predetermined temperature upon being subjected to the second predetermined temperature. The first temperature indication material and the second temperature indication material share a common interface extending longitudinally along the elongated stick.
