Turbidity is the cloudiness or haziness of water caused by large numbers of individual particles that are generally invisible to the naked eye. Traditionally samples are taken and the actual turbidity assessment is performed visually by lab personnel or with a multitude of bench-top style turbidity meters. But our ultraportable turbidity meter can measure readings on site and provide a more representative assessment of the actual process conditions. Turbidity is one of the critical parameters observed while evaluating water quality. There are guidelines and standards provided by international institutions for turbidity of water.
