Reading hold
Manual
Calibration is
successful, but
reading is not
accurate
Aged probe
Replace the probe.
Air bubbles around the
sensor
Make a quick stir in the solution to remove air bubbles.
Clogged junction
Clean the probe with cleaning solution, then soak it in
3M KCL soaking solution overnight
Comparison with other
testers, test strips, or
drop tests
To compare with other testers, make sure to perform a
2-point calibration for all testers in the same standards,
then test a 3rd point. Whichever gives more accurate
reading in the 3rd point standard is the most accurate
one.
Test strips or drop
tests’ accuracy is not
comparable to pH
meters’.
