10-5.3. Temperature Probe
No special precautions are required. Sensor can be stored dry or wet, as long as solutions in contact
with the probe are not corrosive (for example, chlorine bleach).
10-5.4. Conductivity Probe
No special precautions are required. Sensor can be stored dry or wet, as long as solutions in contact
with probe and conductivity electrodes are not corrosive (for example, chlorine bleach). However,
it is recommended that the sensor be cleaned with the provided brush prior to long term storage.
10-5.5. DO Probe
Rapid Pulse dissolved oxygen sensors should always be stored with a membrane and electrolyte in
place and in such a way that the drying out of the electrolyte on the probe face is minimized. For
long-term storage, the medium should be water rather than the moist air used in interim storage.
Two long-term storage methods are equally acceptable:
1. Remove all probes other than dissolved oxygen, conductivity, ADV, and temperature from the
ADV6600 and seal the vacant ports with the provided port plugs. Leave the electrolyte and
membrane in place on the dissolved oxygen sensor. Fill the calibration cup with water (tap,
deionized, or distilled are equally acceptable) and insert the sonde. Make certain the water level
is high enough to completely cover the DO sensor. Seal the vessel to prevent evaporation of the
water. At the end of the storage time, remove the existing membrane and replace it using new
electrolyte.
2. Remove the dissolved oxygen sensor from the ADV6600 leaving the electrolyte and membrane
in place. Store the probes in water (tap, deionized, or distilled are equally acceptable) in a
beaker, flask, or other vessel of the user’s choice. Be sure not to damage the membrane or
the probe tip when placing the probe on the bottom of the vessel. If possible cover the
vessel with parafilm or plastic wrap to minimize evaporation of the water during long-term
storage. Monitor the water level in the storage vessel periodically and replenish if loss due to
evaporation occurs. At the end of the storage time, remove the existing membrane and replace
it with a new one.
10-5.6. pH and ORP Probes
Remove the probe from the ADV6600 and seal the vacant port with the provided plug. Place the
probe in the storage vessel (plastic boot or bottle), which was in place on delivery, with a solution of
two molar (2M) potassium chloride (KCl). Make certain that the vessel is sealed to prevent
evaporation of the storage solution.
