Abstract

The invention proposes a pH monitoring device 10 comprising a chamber 107 for containing a solution; a polymer 105 being immersed in the solution, wherein the physical state of the polymer is changeable in dependence on whether the pH of the solution exceeds a threshold value; and a detector 109 for detecting the change of the physical state of the polymer.
