The Sulphate MINIKIT is a Turbidity Based test kit for the determination of Sulphate levels between 40 and 200 mg/l.
The Turbidity method uses a calibrated two section tube and tablet reagents. A tablet is added to the water in the tube to make a turbid solution. A black dot on the base of the tube is lowered until it is no longer visible, at which point the result can be measured using the scale on the tube.
