下面讨论的多针孔脱气（MPD）系统是一种将水中溶解氧浓度降低到超声研究可接受水平的廉价方法。超声波测量和操作的水脱气方法有几种。然而，这些脱气系统中的许多购买昂贵且复杂，有时需要相当大的维护。这里描述的系统非常适合在循环应用中对大量水进行脱气。它在5小时内将80升水脱气至低于4 ppm O-2，在24小时内脱气至约2 ppm O-2。它还可以方便地收集去除的气体。在撰写本文时，该系统需要一个标准泵和大约10美元的硬件供应。
The multiple pinhole degassing (MPD) system discussed below is an inexpensive method for lowering the dissolved oxygen concentration of water to levels acceptable for ultrasonic research. Several methods of degassing water for ultrasonic measurement and operation are available. However, many of these degassing systems are expensive to purchase and are complex, sometimes requiring considerable maintenance. The system described here is ideal for degassing large volumes of water in circulating applications. It degasses 80 liters of water to below 4 ppm O-2 in 5 h and to about 2 ppm O-2 in 24 h. It also enables easy collection of removed gases. At the time of this writing the system requires a standard pump and about ten dollars of hardware supplies.
