isolated from all connecting piping, the equipment is depressurized, the contents have
been drained, and the equipment is cool.

General Description:
Sentry® Drip Pot Assemblies are ideal for collecting liquid samples for analysis. Drip
pots are constructed from corrosion resistant 316L stainless steel and incorporate
a needle valve on the main chamber to release excess gas pressure. A liquid
sample can then be safely drawn from the lower ball valve. An optional corrosion
coupon allows for simultaneous corrosion analysis and liquid collection. The
corrosion coupon is attached to the bottom of the assembly with a Fixed Coupon
Holder Plug.
Installation
Read instructions thoroughly before installing or using equipment. Contact your
representative or factory customer service if you have any questions. Failure to follow
these instructions could result in serious injury or death.
