100 strips per pack.
These products have been developed in order to offer improved accuracy in specific industries or uses.
The strips are manufactured to have a unique single pad system of impregnated paper, which allows the resultant color change to remain up to 5 times longer when compared to the standard papers. These strips enable the pH value of a solution to be indicated cost-effectively and quickly, measuring in intervals of 0.5 pH
