The VitaLink ESSENTIALS pH test indicator kit is available as narrow or wide spectrum. It uses a solution known as a universal indicator to change a small sample of your solution to a different colour. The colour is then to be compared to the spectrum chart to indicate your pH level.
Spectrum is capable of measuring solution between pH 5.6 and 7.4 at increments of 0.2
