*When using ppm measuring scale for compounds other than
NaCl, refer to appropriate chemistry handbook for reference
solution formulation.
2.
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 tem-
perature differences, this may take up to 30 minutes.
NOTE:
Suspend the sensor to prevent it from touching
the container.
Simply laying it into the con-
tainer will produce calibration error.
If the
sensor is tee-mounted, use a smaller container.
Ideally, convert a tee of the same size and
material as the mounting tee into a calibration
container by sealing two of its ends.
