DPD tablet, water test kit, water treatment chemicals

A widely used type of test method for domestic pools is the dip cell or pooltester. This consists of a small plastic block with one or more cells into which the water sample is added. Coloured scales are provided next to each cell, showing the value of the measurement against the colour. In addition to chlorine and bromine, these are often used, with the correct tablet, to measure pH and alkalinity.
