Replacing Anti-Foulant Devices (SBE 16plus, SBE 19plus)
The SBE 16plus and 19plus (moored option) have an anti-foulant device cup
and cap on each end of the conductivity cell. A new SBE 16plus (or moored
option 19plus) is shipped with an Anti-Foulant Device and a protective plug
pre-installed in each cup.
Wearing rubber or latex gloves, follow this procedure to replace each Anti-
Foulant Device (two):
1. Remove the protective plug;
2. Unscrew the cap with a
5
/8-inch socket wrench;
3. Remove the old Anti-Foulant Device. If the old Anti-Foulant Device is
difficult to remove:
• Use needle-nose pliers and carefully break up material;
• If necessary, remove the conductivity cell guard to provide
easier access;
4. Place the new Anti-Foulant Device in the cup;
5. Rethread the cap onto the cup. Do not over tighten;
6. Replace the protective plug if not ready to redeploy.
AF24173 Anti-Foulant Devices
contain bis(tributyltin) oxide.
Handle the devices only with
rubber or latex gloves. Wear eye
protection. Wash with soap and
water after handling.
Read precautionary information on
product label (see Appendix V)
before proceeding.
It is a violation of US Federal Law
to use this product in a manner
inconsistent with its labeling.
One of the anti-foulant device cups is
attached to the guard and connected
to the conductivity cell. Removing the
guard without disconnecting the
cup from the guard will break the
cell. If the guard must be removed:
1. Remove the two screws connecting
the anti-foulant device cup to the
guard;
2. Remove the four Phillips-head
screws connecting the guard to the
housing and sensor end cap;
3. Gently lift the guard away.
