DUOTEST pH 1-12

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.
