Kamco KTK001 Litmus Paper 5 Metre Roll

• To test the strength of chemicals during descaling and after neutralisation.

Method of use: Dip test strip into solution, in direction of arrow, for roughly three seconds, so that all colour zones are immersed.
Compare indicator zone (unprinted area) to colour scale and read off printed pH value (by holding strip against light, if necessary).

For reference: pH less than 2 = strongly acidic (the pH of Pepsi-Cola or Ribena is 2.6!).

Distilled water has a pH of 7(tap water varies between ca. 6.8 and 7.2 and is generally slightly alkaline in hard water areas).

pH greater than 12 = strongly alkaline.

Before discharging descaling solution to waste,ensure that pH value is at least 5, using Neutralising crystals to increase the pH value if necessary.
