  • "One-click" fully automated operation
  • Pre-wetting function to eliminate measurement errors caused by unsuccessful wetting of Wilhelmy plate or du Noüy ring
  • Easy parameter setting to adapt various measuring standards
  • Video user manual for user-friendly operation
  • Adjustable level of the body
  • Calibration by external weights for periodic inspection of measurement accuracy

Hardware

  • Sedimentation behavior measurement kit
  • Liquid density measurement kit
  • Jacket type sample stage for temperature measurements from +10 to 70°C
  • Heater type sample stage for temperature measurements from ambient to +150°C

Hardware

  • Surface tension: Paints, inks, additives for coating processes
  • Interfacial tension: Transformer oil, emulsions, surfactant solutions
  • Lamella length: Paint leveling, foaming stability of coatings and fire extinguishing agents
  • Sedimentation behavior: Flocculants used in wastewater treatment, stability of dispersions, such as paints and pigmented inks
