摘　　要：雨量器(计)是降水量的主要观测仪器,为保证其测量结果的准确性,对其进行检定或现场校准是非常必要的。文章主要研制既能对雨量器(计)进行室内检定、又能在户外进行现场校准的雨量器(计)检定仪。检定仪采用能够溯源的计量标准球作为标准器,利用蠕动泵对降雨强度进行流速恒定控制,用电源控制器和蓄电池供电,可实现无交流电的户外降水仪器的现场校准。经过试验和应用分析,其性能优于国内同类产品,符合作为量值溯源计量标准的条件,对雨量器(计)的检定和现场校准具有实用性,可用于自动气象站雨量传感器的现场校准。Rainfall gauges（meters）are the main observation instrument of precipitation.In order to ensure the accuracy of the measurement results,the calibration and field verification are very necessary.A rain gauge（meter）indoor test instrument is devised,which can also carry out calibration in outdoor tests.The calibrating instrument uses the measurement standards traceable to the ball as the standard.A peristaltic pump is used for the constant velocity control of rainfall intensity and a power controller and a storage battery are used to realize the outdoor rainfall instrument calibration without the alternating current.Through the analysis of tests and application,it is found that its performance is better than similar domestic products,and it complies with the measurement standards of traceability for rain gauges（meters）.It is applicable to calibration and field verfication,and can be used for the field verification of rainfall sensors in automatic weather stations.
