So, I just purchased a digital refractometer because my handheld had years of pretty good use, so I thought. My handheld measures my salinity at 1.025 my new digital reads at 1.028. I tested the calibration solution and it also reads at 1.028? My sps seems really dull, so my question is should I lower my salinity comparable with my digital readings? Is 1.028 to high?
The Aqua Craft calibration fluid is 35ppt which is 1.028 not 1.025, the meter is making the correct reading. The fluid that comes with the Milwaukee is 1.025. I had the exact same thing happen to me when I bought this unit and thought it was off but it was me that wasn't thinking straight!
I'm convinced with the Milwaukee 1.028 = 1.026. I've tested 3 different calibration fluids and compared my GHL conductivity probe with the ICP test from ATI. I think it's having to calibrate it with rodi water that throws it off. I just use 1.028 as my reference point now.
Since when does 35 ppt = 1.028? Everything I'm seeing on the conversion says 35 ppt = 1.026
