Surfactants are produced in large quantities and are widely used in many applications. Due to their common use, surfactants are introduced into the water supply through domestic and industrial drains.

Surfactants are harmful to water treatment plants, due to the scum that is created
by emulsifying oil and grease. So, by law, surfactant concentrations must be monitored in wastewaters.

The HI 96769 measures anionic surfactants in drinking, surface and waste waters. The meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit a cuvette with a larger neck making it easier to add both sample and reagents. The cuvette is made from special optical glass to obtain best results.
