Sentry MIL Manual In-line Sampler

Part #
Sentry MIL Sampler

The Sentry MIL manual low emission sampler is ideal for sampling liquids in-line in refining, chemical, petrochemical and nuclear applications without exposure to the operator. The sampler's unique features include a close-coupled ball valve specifically designed to provide low dead volume in the sample flow area, ensuring representative samples from flowing process lines at pressures up to 2200 psig (150 barg). Additionally, the pressure drop of the flowing fluid through the sampler is low, and no valve stems or other components pass through the sampling stream.

For nuclear applications, the Sentry MIL sampler normally is used to collect primary side (RCS) samples for laboratory analysis. However, it also can be used to collect samples on secondary side (PWR) or turbine building side (BWR).
Direct in-line liquid sampler with flow through sampling of liquids/light slurries in pipes and process lines.
