    Patent number: 6170983
    Abstract: A thermometer stem is inserted into a thermally controlled receptacle housed by the calibrator to bring the thermometer to a calibration temperature. A socket in the housing engages and holds the adjustment nut of the thermometer so that the casing of the thermometer can be adjusted while the thermometer remains inserted in the calibrator. The socket includes multiple openings of progressively smaller dimension to allow calibration of thermometers using different size adjusters without having to attach or remove an adapter. A wrench can be included for rotating thermometer casings, enhancing ease of use of the device.
