摘要
恒温水浴设备种类较多,且形状各异,但目前尚未有相关的国家计量校准规范。因此,本文从工作空间试验物品放置的角度出发,提出基于中心点的设定温度误差、显示温度误差等参数的校准方法。同时,对5家不同类型的国产恒温水浴设备和4家计量检测机构进行了比对试验,并对中心点设定温度误差进行不确定度评定。
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 temperature error at the center point was evaluated.
