1. Hold the pH Probe vertically so that the solution
will not spill out of the bottle.
2. Unscrew the plastic cap and remove the bottle.
Keep the storage solution for later use.
3. Push the bottle cap and the rubber washer up the
pH probe shaft to keep them out of the way

Place the sensor in a solution
Place the end of the pH probe in a solution when
taking measurements. Make sure that the bulb at the
end of the probe is completely immersed in the
solution.
Note: Do not immerse the BNC connectors in
the solution. The connectors are not rust proof and
can corrode.
To keep the probe in place, it is recommended to use
an Electrode Support (PS-3505). The Wireless Drop
Counter (PS-3505) can also be used to hold the probe.

Calibration
ation
Calibration is not always necessary, especially if you are measuring a
change in pH rather than absolute pH values. However, the pH Sensor
can be calibrated if more accurate measurements are necessary. See
the SPARKvue or Capstone online help for instructions on how to
calibrate the sensor.

Storing the sensor and pr
oring the sensor and probe
obe
After each use, place the pH probe in the storage bottle filled with the
storage solution. The bulb at the end of the probe must be fully
immersed in the storage solution. It is not recommended to store the
probe dry since the probe will lose responsiveness. If needed, probe
restoration instructions are provided online on the Wireless pH
Sensor product page.
Replacement pH Storage Solution (SC-3507) can be purchased if any
solution is lost due to spillage or evaporation. If you wish to make
your own storage solution, instructions are provided online on the
Wireless pH Sensor product page.
For long-term storage, remove the battery to avoid damaging the
sensor due to battery leakage.

To replace the battery:
1. Insert a coin into the battery compartment door. Turn
counterclockwise until the indicator (C) is aligned with the second
mark (B).
2. Remove battery compartment door, O-ring gasket, and battery.
3. Insert a new CR2032 battery in the compartment with the positive
(+) side facing up.
4. Insert the O-ring gasket in the compartment.
5. Place the door on the sensor, aligning the indicator with the
second mark. Turn the door clockwise until the indicator is
aligned with the first mark (A).
