To calibrate a dew - point hygrometer , a stream of low flow rate air , generated by a standard humidity generator and at the specified dew - point temperature , is passed through both the uut and reference dew - point hygrometers which are then compared 由标准湿度产生器产生的低流速定值露点温度的空气会流经被测试仪器及参考露点湿度计，然后互相对比，从而校正露点湿度计。
