C. Conductivity Measurements
1.
Turn the unit on. Place the probe in the solution to be measured. Immerse the
probe (at least 2” to 3” or 5~7cm from the tip). Shake the probe lightly to remove
any trapped air bubbles in the conductivity cell.
2.
Press “Mode” key to enter the desired measurement mode. The message “rAGE”
(range) may appear briefly on the display indicate auto-ranging; this is normal.
Allow temperature to stabilize before taking measurements.

● Salinity is
>70.0 ppt.
Ensure the probe is immersed
at least 2”~3” or 5~7cm from
the tip, below the surface of
the sample/standard solution.
Allow sufficient time for the
electrode and Temp probe to
stabilize.
Recalibrate with correct value
for the conductivity standard.
Replace conductivity
