lately I seem to have some issue in deciding which shows me the correct reading.
I calibrated all three with their own recommend calibration solutions.
after calibration, i dip in the 35ppt solution and all show the correct reading (34.9 in my case)
Now the issue is.
apex prob on DT shows 29.5 to 30.4 ppt
on the same DT hanna shows 34 ppt
refractometer shows near 34ppt
If i think apex prob is the issue, i dip the prob into 53ms solution it shows 34.9, i also dip in the hanna's 35ppt solution and it shows 34.9
What is happening?
