独联体国家开发了便携式渗漏部位检测装置ＦＤ１。ＦＤ１适用于防水层上依然存在各种绿化层、保护层等材料。 操作人员在屋面立墙边，做为脉冲传感的负极的检测管接触其湿透表面，正极与建筑物的钢筋混凝土、金属屋面板连接在一起。用４０Ｖ的脉冲电流通过浸湿透的保湿层边缘部 The CIS countries have developed a portable leak detection device FD1. FD1 is suitable for all kinds of materials such as green layers and protective layers on the waterproof layer. The operator is at the edge of the wall of the roof, and the detection tube, which is the negative electrode of the pulse sensing, contacts the wet surface, and the positive electrode is connected with the reinforced concrete and metal roof of the building. Using a pulsed current of 40V through the soaked edge of the moisturizing layer
