Abstract：This paper discusses the influence of key test points on humidification output value of humidifier， and analyzes the test result. According to it analyzes the test elements affecting the humidification output， such as the temperature of the input gas and the ambient humidity ， obtains the humidification outputvalue through testing，analyzes the influence ofthechanges of various factors onthe humidification output value，and investigates the stabilityof the humidification output bytesting the continuous operation time of the humidifier. The results show that if the temperature of the input gas changes with the ambient temperature， the correction factor of the humidification output will also rise with the increase of temperature； The influence factor will increases with the increasing ambient humidity； the humidifier runs for a long period of time， and the value of the humidificationoutput willfluctuatebut the overallchange isnot signifcant and iswithin the range of compliance with the requirements.This paper describes and tests thekey points of the humidifer humidification output，whichplaysacertainguidingroleinthetestoperationofthehumidifierhumidifcationoutput，andcan provide technical support for manufacturers or testing institutions in the test.
