Secchi Disk - 20cm Ø, 4m cord, eye hook, nylock, self-weighted
A Secchi disk is a very cost-effective tool used to measure water clarity in any water body it determines turbidity or degree of visibility. Measure from a dock, boat, or platform, this self-weighted steel Secchi Disk 1.5kg, 20cm (8-inch, 3.3Lbs) comes with 4m (13ft) marine rope. The Secchi disk is slowly lowered down in the water. The depth at which the disk is no longer visible is taken as a measure of the transparency of the water. This measure is known as the Secchi depth and is related to water turbidity. This heavy duty Secchi disk will last you a lifetime, unlike plastic disks.
