I just received a brand new Milwaukee refractometer and the reading for the standard solution is off. The standard is 1.025, but reading is coming in at 1.023 no matter how many times repeat and/or recalibrate.
I haven't tested my tank water yet because I don't know what to do with this
information. Could the solution be off? That doesn't seem right.
Maybe the next step will be to test with a manual refractometer and see is its 1.023 or 1.025 and compare to the Milwaukee.
If the instrument is coming in at .002 off consistently would this be grounds to return the unit? Can it be recalibrated to read correctly from home? And since it's consistent.. How would this translate into tank readings? Would they also be off by .002 or would it translate differently at another salinity?
Sorry for all the questions, but this is my first time using the unit and I'm just trying to get an idea of how to interpret this
