I can’t get accurate results even after recalibrating. I switched to a Refractometer and have had much more accurate results (for less money)
Pretty good, pretty good calibration, solution makes it easier.

Don't get it. Accuracy is way off, almost cost me my corals.
Very Accurate. I Calibrate once a month.
