标准范围

包括通过电化学电池进行的程序，该电池通过气体渗透膜与样品隔离。根据所用探头的类型，可以测量氧浓度、饱和度百分比或两者。该程序适用于现场测量、连续监测和实验室测量。这是高颜色和浑浊水域的首选程序。它适用于天然、废水和盐水。

Includes a procedure by means of an electrochemical cell which is isolated from the sample by a gas permeable membrane. Depending on the type of probe employed measurement can be made either as concentration of oxygen, percentage saturation or both. The procedure is suitable for measurements made in the field and for continuous monitoring and in the laboratory. It is the preferred procedure for highly coloured and turbid waters. It is suitable for natural, waste and saline waters.
