• pH indicator paper • Wide range, in strips or rolls • Incrementing by 0.2 or 0.3 pH • For the rapid testing of clear, cloudy or coloured solutions • Keep in a dry, dark place
• pH indicator strips "non bleeding" • For fast reading • Ideal for measuring the pH of weakly buffered or highly alkaline solutions • The indicators do not bleed because they are bound to the cellulose fibres, no pollution, so the solution can be reused for other determinations • Reliable measurement of weakly buffered solutions because the strip can remain immersed in the solution until the definitive colour is obtained • Different coloured indicator zones which are sufficiently separated to ensure a clear reading • Rigid plastic strip for improved handling • Transparent plastic box containing: 100 strips 6 x 80 mm + colour scale • Dim.: 6 x 80 mm
• CF type strips: each plastic strip has 4 segments of different coloured test paper. The combination of colours allows a visual determination. • CS type strips: each strip has a central segment with indicator and 8 other coloured segments - or more - identified by their corresponding pH. The pH can then be read directly by comparing the test strip with the coloured bars. Ideal for testing coloured solutions which may alter readings. • TC type dispenser: each strip has 3 separate indicator zones. The unique combination of the colour change for each test is then compared to a reference card printed on the dispenser to allow a fast and accurate reading. • SR type dispenser: a full range of pH papers for this dispenser.
