Need to determine how clear the water is? Seeing may not be believing! Measure the turbidity or degree of visibility of the water you’re testing with our secchi disk. Many things have changed in the past 70 years - but not the Wildco® secchi disk! We’ve used the same white acrylic in its manufacture since our founding in 1938. Confidently compare your results with data from earlier decades!
