• 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.
