Sentry ISOLOK SAH Automatic Sampler

Part #

The Sentry ISOLOK SAH automatic point sampler is an extended stroke sampler for collecting flowable free-falling materials within chutes or slides. A three-inch plunger stroke collects samples inside heavy-body or double-wall vessels such as mixers, dryers and reactors.

An air cylinder extends a single plunger into the process material, then immediately withdraws, carrying a fixed amount of sample trapped in an annular ring between plunger seals. Process or flow ports are always closed, preventing leaks or product loss. There are no tubes or passages to become clogged. The gravity-discharged sample is transferred directly to a closed container.


  • Collects samples from slide or vertical drop chutes or direct from open processes
  • Single moving part collects accurate and repeatable 40 or 50 cc sample volume
  • Simple gravity-discharge design for powder, flakes or pellets up to 5/8 in (16 mm) without shearing or degrading sample material
  • Rugged 316 stainless steel construction
  • Field-replaceable, application-specific seals include EPDM, polyurethane elastomers and more
  • Extended-stroke plunger ideal for sample collection inside heavy-body / double-wall vessels
  • Clamp ferrule for easy installation and maintenance
  • ATEX-compliant models available
