Hi dear the calibration is also one of the system
suitability test,whether the system working satisfactory or
not physically so when you do the calibration for pH meter
with standard pH buffer solution (which is from NIST-it may
accurate solution for actual pH)and once if your instrument
has calibrated,you can cross verify your insrument against
those pH buffer solution (NIST) and the acceptable range is
+/- 0.02 then you can conclude for ?
once if temperature raises the pH will decrease and its not
all cases
