Hi,

I am checking the calibration on several new Hydros21. I don’t see how to calibrate the sensors themselves, so it would be useful to display (at the data portal) a calculated variable for the Hydros21 in addition to the specific conductance coming from the sensor. Calculating the variable in the logger code looks doable to me thanks to t…[Read more]

Thanks,

Great work! Cannot wait to get some of the wipered turbidity sensors in the field.
