1. A temperature control device comprising:

  • a housing, a well within the housing configured to receive an object, at least one fluid port in the housing configured to provide fluid access to the well;

    a thermal element in heat exchange communication with fluid in the well;

    a temperature sensor disposed in the well at a location to be covered and uncovered by fluid in the well as the housing portion moves;

    an agitation system coupled to at least a portion of the housing to cause fluid flow within the well to periodically cover and uuncover the temperature sensor with fluid within the well; and

    a controller in communication with the thermal element, the temperature sensor, and the agitation system and operative to control the thermal element in correlation with temperature readings from the temperature sensor and movement of the agitation system, wherein temperature readings when the temperature sensor is covered with the fluid correspond to peak temperatures in the temperature data.
