This Minikit is for testing Total Alkalinity. It is based on a tablet count method. Total
Alkalinity, also known as Alkalinity M, is the acid demand of the water to the colour
change of the methyl orange indicator (pH 4.3). Chemically it represents the alkalinity
mainly from the presence of hydroxides, carbonates and bicarbonates in the water.
