Request Information
  • The ability to back purge the sample point ensures optimal retrieval of a representative liquid sample.
  • The needle purge ensures there is no residue or build up in the needle after sample retrieval.
  • The DPM type sampler in back & needle purge configuration allows purge gas to flow through the sampler ensuring a fresh sample and finally to purge the needle assembly at a recommended maximum operating pressure of 8 bar.
  • This liquid sampler offers one-handle operation, providing safety for the operator and zero emission.
