Johnsons BEER pH indicator strips
The pads on these polypropylene (environmentally friendly) strips are prepared as a non-bleed system, therefore the resultant colour change will remain far longer and readable until the pads are dry. These strips provide an accurate method of measuring the pH of a solution and produce high quality results each time.
