Reply To: Hydros-21 Depth Temp Compensation

We recently received a Gen 2 Hyrdos 21 CTD sensor from Meter Group and have confirmed that it works just fine with the Mayfly Data Logger, and using our Modular Sensors library, with just a very small adjustment made to the library.  We’re in the process of updating that now, so you should be good to order them and use them when they arrive.
