A simple and undeniable indicator of water quality change

The measurement of turbidity is a key test of water quality: drinking water – waste water monitoring – industrial waters and more…

Reliable turbidity monitoring is an essential component of drinking water production, and public health and safety organizations around the world recognize the importance of measuring this parameter.

A sudden change in turbidity may indicate an additional pollution source (biological, organic or inorganic) or may signal a problem in the water treatment process.
