GB/T 6908-2008 specifies the measurement method of conductivity for boiler water and chilled down water. In industrial production, the water quality of boilers and chilled down systems directly affects the operation and safety of equipment, and conductivity is a key water quality indicator. The standard elaborates the measurement process and provides unified specifications for relevant industry practitioners. By accurately measuring conductivity, water quality changes can be effectively monitored, helping enterprises to adjust water treatment measures in a timely manner, ensuring the efficient and stable operation of equipment, reducing the risk of equipment corrosion, and promoting the standardization of industrial water treatment.
