  • Test procedures are fully automatic
  • Data automation
  • Semiconductor for refrigeration, makes determination rapid
  • Solidifying point and pour point determination
  • LCD and graphic display
  • It can track and display the real-time temperature, and simulate the test status intelligently

It can be widely used in oil refineries, oil stations and other relevant institutions. It can be mainly used to determine the solidifying point and pour point of light oils which have good flow ability and low viscosity.
