316 SS Industrial Process Sampler

We understand the need for a clean, representative, trouble-free sample for on-line process monitors. Conventional filtering techniques accumulate dirt particles on the filter media until the media clogs and is replaced. The tangential filtration technique used in the model 521, however, passes virtually all of the particulate through the unit untouched.

Bypass sampler with integrated PTFE filter element to provide a filtered sample to a process analyzer. Approximately 90% of process flow bypasses filtration and 10% flows to the sample outlet.  Materials: 316 Stainless Steel and PTFE.


  • simple set up – 4 connections
  • reduced analyzer maintenance with filtered samples for processes up to 100 °C (212 °F) and 340 kPa (50 psi); 100 % retention for particles ≥ 50 microns, 50% retention at 10 microns
  • backflush port eases maintenance of filter element and extends replacement frequency
