DSS70A Portable Sampling System and Sampling Cells for DM70

The Vaisala DRYCAP®Portable Sampling System provides a compactsolution for field checking dew point where direct measurement isdifficult. Typical applications for the sampling system are metaltreatment and plastics drying processes.

  • A compact solution for sampling from hot or dirtyprocesses
  • Enables measurement from both pressurized processes andprocesses at atmospheric pressure
  • Vaisala DRYCAP®sensor with patented autocalibration function
  • Low maintenance need due to excellent long-term stability
  • NIST traceable (certificate included)
