Cleaning
Probe and Front End
Clean the Aqua TROLL with water and a soft brush or plastic
scouring pad, or soak overnight in a mild acidic solution, such as
household vinegar.
If the pressure ports of the Aqua TROLL 200 in the front end are
clogged with silt or mud, try the following:
• Agitate the instrument vigorously in a bucket of clean water.
• Apply a gentle stream of water from a wash bottle.
• In severe cases, remove the nose cone and clean out the
holes with a soft brush or pipe cleaner.
To avoid damage to the pressure sensor diaphragm, do not insert
any object into the sensor opening or attempt to dig out dirt or
other materials.
If contamination cannot be removed using the
recommendations above, please contact In-Situ Inc. for cleaning.
