B. Thoroughly rinse the clean sensor in de-
ionized water. Then immerse the sensor in the
prepared reference solution.
Important: Allow
the sensor and solution temperatures to
equalize.
Depending on their temperature dif-
ferences, this may take up to 30 minutes.
NOTE:
Suspend the sensor to prevent it from
touching the container.
Simply laying
it into the container will produce
calibration error.
If the sensor is tee-
mounted, use a smaller container. Ide-
ally, convert a tee of the same size and
material as the mounting tee into a
calibration container by sealing two of
its ends.
