PTB210 air pressure sensor check test and results verification as a period verification standard

In the quality management system, it is necessary to select the instruments with stable performance as the periodic inspection standard, and regularly carry out the periodic inspection on the standard. At present, PTB210 air pressure sensor produced by Vaisala company is easy to be used in our station, and there are corresponding verification regulations. We test and evaluate PTB210 air pressure sensor from two aspects of repeatability and stability by combining the analysis of uncertainty evaluation and laboratory verification. Finally, we verify the validity of data by transfer comparison method.
