My Hanna reader ways 31.5 ppt and my refractometer says 35. annoying :(
the Hanna electrothingy has a lot battery indicator, could that be the problem?

is that a safe range for me to just move forward with or do I need to fix it ASAP? What’s considered a safe range?

So what you want to do is a calibration before you test with it. I beleive they both calibrate different with different fluids
