Sentry DPA Series

Part #
Configure Your DPA

Sentry DPA Series offers easy-to-use drip pot assemblies to collect samples within a pipeline or other pressurized system for the purpose of examining and measuring corrosion products and other contaminants, without interruption to the system. Drip pot assemblies collect the samples for analysis using a container with an interior reservoir for receiving a liquid sample, and a valve assembly coupled to the drip pot.

Constructed from corrosion resistant 316L stainless steel, each Sentry DPA Series drip pot assembly incorporates a bleeder valve on the main chamber to relieve process pressure so the sample then can be drawn safely from the sample valve. An optional corrosion coupon can be attached to the bottom of the assembly with a fixed coupon holder for simultaneous corrosion analysis and sample collection. For easy sample collection within a pressurized system, the Sentry DPA Series is the best choice for corrosion monitoring.
