The Turbidity Tube with Secchi Disk is a simple, portable instrument used to estimate water turbidity by measuring the depth at which a black-and-white Secchi pattern is no longer visible through a water column. Designed for field and laboratory use, the tube provides a quick and economical method for assessing water clarity in lakes, rivers, ponds, reservoirs, aquaculture facilities, and environmental monitoring programs. It is widely used for educational demonstrations, watershed studies, and routine water quality assessments.
