  • The ability to create a vacuum in the sample bottle by a venturi unit ensures optimal retrieval of a representative, contamination free sample from processes at vacuum conditions or atmospheric pressure.
  • The S32 type of sampler in back purge configuration allows a gas to purge the sampler and process connection prior to sampling ensuring a fresh sample.
  • All S32 type of samplers offer a one-handle operation by multiple valves.
