纯蒸汽饱和度怎么测？

快活王

EN285上有明确的规定和做法啊，百度一下。

最好买仪器去测，整体不到10万

EN285里面，针对纯蒸汽质量测试，只有三个测试项：
Steam quality tests: Non-condensable gases; Dryness value; Superheat

不凝性气体Non-condensable gases：The steam quality test, non-condensable gases, is used to demonstrate that the level of non-condensable gases contained in the steam will not prevent the attainment of sterilization conditions in any part of the sterilizer load.

干度Dryness value：A continuous supply of saturated steam is required for steam sterilization. Excess moisture carried in suspension can cause damp loads, while too little can not prevent the steam from becoming superheated during expansion into the sterilizer chamber.

过热Superheat：The steam quality test, superheat is used to demonstrate that the amount of moisture in suspension with steam supplied from the service supply is sufficient to prevent the steam from becoming superheated during expansion into the sterilizer chamber.

你说的饱和度，应该就是指干度吧？

纯蒸汽这三项质量测试有专门的测试仪，论坛里有奥星的，他们有销售这仪器，可以咨询他们哈。EN285的“22  Steam quality tests”项下有详细的测试方法，自己能做出来测试仪也是可以的哈

有一套专门的设备，三大指标都可以测。
