Scope
This part of GB/T 20432 specifies a general test method for determining the pH of photographic-grade chemicals solutions (with an accuracy of ±0.1 pH). This method is not intended for monitoring the pH of compound solutions, such as developing solutions, that are directly used in photographic processing.
