for underwater operation.

defects that may exist on the O-ring.

moisture, dirt or material that can damage the O-ring, battery or battery
connectors.
Condensation in FlowTracker2 Housing 11.3.5
Moisture in the air can potentially damage FlowTracker2 electronics if allowed to
condense inside the handheld housing.
a) The handheld is shipped with a desiccant pack inside to absorb moisture,

Zinc Anodes for Corrosion Protection 11.3.6
When using the FlowTracker2 in salt water, additional precautions must be taken to
prevent corrosion.
a) A sacrificial zinc anode should be installed on the probe (attached to the metal
portion of the probe stem),
b) Anode condition should be inspected regularly, and the anode should be replaced
when necessary. Zinc anodes are available from SonTek,
c) To check anode condition, try to chip away part of the anode with a screwdriver. If
large portions of the anode easily fall away, the anode should be replaced,
d) The probe and cable should be thoroughly rinsed with fresh water after each use.
