描述：

For accurate determination of the pH in water samples and for adjusting the pH of a sample during analysis:

Significantly superior to other pH papers when it is important to prevent analytical errors during the testing of highly buffered solution.
Weakly buffered solutions can be tested by immersing the strips in them until the final color of the reaction is attained.
The indicator dyes do not contaminate the sample to be tested so it can be used for further analyses.
