The life of boilers and related components depends heavily on the quality of water treatment. To control this, reliable measurements must be made. These measurements on high purity water are more difficult than on conventional water because the properties at higher purity are significantly different Sample conditioning, signal stability and temperature compensation are all handled differently when dealing with high purity water. A background of the basic measurements of conductivity, cation conductivity, pH and dissolved oxygen, along with special precautions required for successful high purity water measurements are presented.
