Conductivity probe currently reads ~31.
I have calibated it automatically with the same result (reads 35 in calibration fluid)
I have calibrated in manually with 2.2 offset with the same result (reads 34-35 in calibration fluid)
I have calibrated my refractometer with calibration fluid (35ppm) but that shows the water to be at 35.
So either my probe is wrong and the water is at 35ppm
or my refractometer is wrong and the water is at ~31ppm.
or I've lost my marbles.
What should I trust?! and what should I do next?
