I just purchased a new unit and i finished with the calibration set the probe in the tank overnight and in the morning i see the salinity is very low i take out my refractometer and salinity is good
I dried the probe during the dry time
I shook the probe to release air bubbles
I don’t know what else im doing wrong or is the probe messed up
So right after the calibration it showed me the calibration fluid is 45.3 i left the probe in the calibration fluid and it changed to 35.1 it doesn’t make sense
