There are many types of constant temperature water bath equipment and different shapes,but there is no relevant national measurement calibration specification.Therefore,from the perspective of test items placement in the work space,this paper proposes a calibration method based on the central point of setting temperature error,display temperature error and other parameters.At the same time,5 different types of domestic constant temperature water bath equipment and 4 measurement and testing institutions were compared,and the uncertainty of the set tem-perature error at the center point was evaluated.
