Qualitative pH Tests
These papers do not require the need for a colour chart as their purpose is to demonstrate qualitative analysis in a simple ‘yes’ and ‘no’ manner. They will not provide accurate pH measurement but will change from one colour to another at a set pH value, depending on the paper. These user-friendly test papers are suitable for many industrial and educational applications.
