These are special products for determination of pH in coloured solutions. The special feature of these papers is that the indicator fields and the colour scale are joined on one strip. The strip has to be fully immersed in the sample. If the solution is coloured, the colour shift works the same way on the indicator as on the scale, thus compensating for it.
