Abstract
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.
