In order to solve the lack
of relevant evaluation research on the accuracy of HMP155A humidity sensor
calibration results in the past, this paper designs the corresponding
experimental scheme, and obtains the corresponding calibration results
according to the experimental scheme; Then the measurement uncertainty of the
indication error in the calibration results is evaluated by GUM, and the
corresponding extended uncertainty U95 is obtained. Finally,
according to the requirements of JJF1094-2016 characteristic evaluation of
measuring instruments, combined with the calibration results and the actual
situation of U95, the conformity of the indication error of
calibration is determined. The result is that each calibration point of the
sensor meets the requirements of conformity determination and is within the
qualified range. This research effectively makes up for the blank of the
previous research on the conformity determination of the indication error of
the calibration results and has strong theoretical and practical significance.
