This correlation can be roughly approximated with a turbidity tube. It's not an instrumented approach like the nephelometer, but if you just want a rough order of magnitude of the logarithmic scale, it'll do.
Check out: http://www.waterwatch.org.au/library/module-4/turbidity.html#3 for info on how it relates to the instruments and secchi disks. Then look at: http://clean-water.uwex.edu/wav/monitoring/turbidity/tubedirections.htm for the rough scale of distance vs. visibility. Be cool, don't drool...
