- Scope
- This standard specifies the method for measuring the pH value of groundwater using the glass electrode method. This standard is suitable for measuring the pH value of groundwater. The measurement range and precision depend on the pH electrode and pH meter selected. The color, turbidity, colloidal substances, redox potential or salinity of the water sample generally do not affect the determination. Temperature effects can be corrected through the temperature compensation device on the instrument. Errors will occur when measuring pH>10 and samples with high sodium ion content. One of the important indicators of the environment.
