Abstract With the construction of prefecture-level meteorological metrology laboratories,the national measurement comparison organized by China Meteorological Administration cannot meet the needs of a large number of prefecture-level measurement laboratories in time.In view of this situation,Sichuan institution of meteorological metrology verification takes the primary pressure laboratory which has participated in the national meteorological measurement comparison as the leading laboratory.The air pressure reserve laboratory,Ganzi metrology laboratory and Liangshan metrology laboratory are taken as the comparison laboratory.By comparison experiment,the consistency of the results of the pressure gauge in the comparative laboratory is verified.The experimental results show that the measurement results of the three reference laboratories are in good agreement with those of the leading laboratory,and the measurement work of the pressure sensor can be carried out normally.This comparison method can also provide reference for the measurement comparison of prefecture-level meteorological metrology laboratories in other provinces.
