Duotest pH indicator papers – featuring two indicator zones for higher accuracy

Duotest indicator paper features two different indicator zones on one single paper.  The zones are separated by a hydrophobic barrier, which effectively prevents mixing of the reaction colours and increases mechanical stability.  Clear colour differences allow you to safely estimate intermediate values, which in turn increases measurement accuracy.

Duotest is available in a variety of different measuring ranges.  Find the ideal test paper for your application!
