Reply To: Alternative to Campbell Scientific OBS-3?

We’re eagerly awaiting the new Campbell turbidity sensors which should be available in late spring or early summer.  In the meantime, there aren’t any other low cost, high quality turbidity sensors that easily interface with the Mayfly except for the Yosemitech ones, which we’re still evaluating for long term performance reliability and accuracy.  Some other people on this forum have used them and might be able to give their opinion of them so far.
