| Resource Description
|
| STUDENT MODEL SECCHI DISK. Constructed from ABS plastic, this 20cm disk is perfect for introducing students to this basic limnological measuring device. Simply lower into water until it "disappears" and record depth to measure clarity. The line differs from the one listed to the left in four ways: the line is not calibrated, line is thinner (more stretch), shorter (48’), and is not accompanied by a spindle for reeling it in. While it does not have all the features of the professional model, it does give accurate readings in shallow waters with minimal currents. #T-6310.
