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.
