Abstract：The repeatability measurement of the error of three kinds of hygrometers under the environmental condition of 25℃ and 50%RH is carried out in this paper.And according to JJF1059.1-2012 Evaluation and Expression of Uncertainty in Measurement,the uncertainty of the indication error is analyzed and evaluated.The mathematical model is constructed.The source of uncertainty introduced by each input component in the model and the calculation method are analyzed in detail.The synthetic uncertainty,degree of freedom and extended uncertainty are calculated.The results show that the environment provided by the verification device has a great influence on the uncertainty of the error of measurement results.
