accuracy class1,0

  • can be used in case of heavy vibrations and high, dynamic pressure loads
  • longer service life due to less wear and corrosion protection of the measuring system
  • various refrigerants measurable with multiple scales
  • DNV- and GOSSTANDART-certified

For simultaneous measurement of vapour pressures and temperatures in refrigeration engineering.
! For measuring gas or vapour, observe the table "Selection Criteria as per EN 837-2" (see appendix)!
