Qualitative pH Tests Strips
Johnson Test Papers offers litmus papers for the routine management of acid or alkali reactions in industry. 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. These user-friendly test papers are suitable for many industrial and education applications
