This standard specifies the determination method of pH value in industrial circulating chilled down water and boiler water. It is applicable to the determination of pH value in the range of 0 to 14. The standard is also applicable to the pH determination of natural water, sewage, except saline water, boiler feed water and pure water. The principle of the method is to determine the pH value of the solution by measuring the electromotive force of the primary battery. The standard details the required reagents, materials and experimental procedures. It is a key technical guide for industrial water treatment and boiler water quality monitoring.
