Abstract:In order to further verify whether the JJG207-1992 Verification Regulation of Meteorological Hair Hygrometer meets the requirements of JJF1094-2002 Evaluation of the Characteristics of Measuring Instruments regarding "conformity judgment of measuring instrument indication error",a set of higher accuracy measuring standard instruments is added on the basis of the prescribed measuring standard instruments in the regulation to calibrate the commonly used meteorological glass mercury temperature gauges,and the error value conformity of the calibration results obtained from different measuring standard instruments is judged separately.The results show that the measuring standard instruments specified in JJG207-1992 Verification Regulation of Meteorological Hair Hygrometer are not applicable,manifested as the inability to directly judge whether the indication error is qualified,or although it can judge the indication error,it needs to be considered whether to expand or not.The impact of certainty and other factors.When using higher-level measuring standard instruments,the qualification of the results can be directly determined based on the indication error.Therefore,it is recommended to select measuring standards with higher accuracy levels when conducting the calibration of mercury-in-glass thermometer,and revise the requirements for measuring standard instruments in the JJG207-1992 Verification Regulation of Meteorological Hair Hygrometer to meet the calibration needs.
