I purchased the calibration set/control sample from Hanna to check against my ULR Phosphate checker.
The control sample was .4 and mine read .37 so within the acceptable margin of error.
Question is will the checker I have always be .03 low on every reading going forward? Just curious
I get it is not a significant difference. Well I guess that depends on who you ask.
