Introduction

The PH test is a method used to measure the acid-baseproperties of a solution. PH is the abbreviation of"hydrogen potential". It refers to the concentration ofhydrogen ions (H+) in a solution. The measuring range ofpH is 0 to 14, where pH 7 indicates a neutral solution, pH less than 7 indicates an acidic solution, and pH greaterthan 7 indicates an alkaline solution.

Representive Results

1. PH value test-potentiometric method

2. PH value test Relationship of pH-E

Sample Requirement

1. The sample should be clean.

The sample should notcontain any contaminants that could affect the testresults.

2. The sample should be stable.

The sample should bestable during the test to ensure the repeatability andreliability of the test results.

3. The sample must meet the requirements of the testmethod.

Different test methods may have differentsample requirements.
