Salinity

The measurement of salinity is based on the Practical Salinity
Scale which uses the EC measurement. If the user has a standard
with known PSU value it may be used to calibrate the conductivity
sensor.
• Select “Salinity” from the “Conductivity calibration” menu.
• Use the keypad to enter the known salinity value of the calibra‑

tion solution. Press

Accept

to confirm.

• Fill the calibration beaker with salinity standard of known value.
• Pour additional standard into a second beaker to be used to rinse the sensor.
• Immerse the sensor into the rinse beaker and raise and lower the beaker to ensure that the EC

sensor channels are filled with fresh standard.

• Place the calibration beaker with standard over the EC sensor and dislodge any trapped gas

bubbles. Screw the beaker into place.

• Wait for the reading to stabilize. The stability timer will count down and

Confirm

will appear.

• Note the temperature and adjust the salinity value if needed.
