Procedure: Small amount of sample is collected in a test tube and an indicator reagent is added to the sample. Use the dropper bottle, the titrant, until the color changes. To calculate the concentration just multiply the number of drops required by the titrant by a simple factor given in the test kit manual.

The test is based on the turbidity method using a single pouch reagent . The test range is 40-200 mg/l as So4. The range can be expanded to 4000 mg/l So4 if the sample will be diluted.Sulphate ions in the sample react with barium in the sulphate reagent and form insoluble barium sulfate turbidity. The amount of turbidity fromed is proportional to the sulfate concentration.
