Abstract : this article lists some notices of the measurement points and their importance in cleanrooms , content focus on ： indoor temperature measurement , humidity survey , exhaust air flow measurement , production line velocity measurement , inside and outside pure room differential pressure survey and the related test equipment for those measurement mentioned above 本文主要介绍了洁净室里需要注意的几个测量点和它重要性，内容包括：室内的温度测量、湿度测量、送风量和排风量的测量、成品生产线上的微风速测量、洁净室内外压差测量等，以及与之配套的测试仪器选择方法。
The distance between supply and exhaust air outlets is so small as to form strong blow and exhaust airflow , so the effect of the buoyant on airflow can be eliminated when supplying hot air in winter , and nearby working environment can be from pollution due to the smaller controlled area , so that an optimal environment effect can be obtained 因送排风口距离小可以形成强劲的吹、吸气流，能克服冬季送热风时浮力对气流的影响，同时由于控制区域小，不污染附近的作业环境，因此可取得漆雾控制的最佳效果。
