I should have worded that differently, and not made such a blanket statement.How do you know that?
The swing arm and glass hydrometer read exactly the same when I test my salinity. The hanna tester I have would read up to 1.028 even after calibration when the other two were at 1.025.
I do realize that hanna has a deviation of .002, so that 1.028 might be 1.026, and factoring in the deviation of .001 of the glass hydrometer the reading of 1.025 might be 1.026.
I just didn't want to be checking and guessing 3 different ways with testers. So now I stick with the two that read the same consistently, so if I see a reading that is off I know to check with the other.
