Seems great at first, then when referenced vs a normal refractometer it had got me putting my salinity 1ppm up. Then recalibrated following all instructions, gave a much lower reading than the refractometer. Recalibrated a third time and it was over again. Really not sure I trust it at all now.

Terrible, need frequent calibration, like very frequent.
This unit has messed up my salinity two times now by falling slowly out of calibration.

I can’t get accurate results even after recalibrating. I switched to a Refractometer and have had much more accurate results (for less money)
