*When using ppm measuring scale for compounds other than
NaCl, refer to appropriate chemistry handbook for reference
solution formulation.
B. Thoroughly rinse the clean sensor in de-
ionized water. Then fully immerse the sensor
electrodes in the prepared reference solution.
Important: Allow the sensor and solution
temperatures to equalize.
Depending on their
temperature differences, this may take a few
minutes.
NOTE:
Suspend the sensor to prevent its
electrodes from touching the container.
Remove any bubbles clinging to the
outer and center electrodes by gently
stirring the sensor in the solution.
Models with a deeper recessed center
electrode require more vigorous stirring.
