Product description

Optical instruments for Secchi Disk           



A fast, easy way to determine turbidity (degree of visibility) in shallow waters. Designed for use in shallow water, the secchi disk works best in a shaded place. Determines the index of suspended matter in the water. The smaller the index, the more suspended material there is. The disk can also be used to measure the depth of light penetration and can derive a rough estimate of the extent of the littoral zone. Kit includes 7-7/8" dia. disk and instructions. The line is included and is 3/16" nylon braided twine.
