4 pad pH Indicator Strips
The pads on these polypropylene, environmentally friendly, strips are prepared as a non bleed system, therefore the resultant colour change remains far longer and readable until the pad is dry. Each strip is long enough with the test pad/s at one extreme to protect the user from the test solution.
For accurate pH readings, these strips use up to 4 different indicator colours and the colours on the enclosed colour chart match the colour and position of each pad on the strip. This allows these strips to provide a rapid method of measuring the pH of a solution while producing high quality results each time.
These strips provide precise pH value as the different colours do not mix Comparator pH Strips are sensitive and small pH changes down to 0.2 pH can result in a clear colour change to distinguish the pH of a solution. Johnson Test Papers Catalogue
