  • "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 ℃
  • Heater-type sample stage for temperature measurements from ambient to +150 ℃
  • Surface tension: Paints, inks, and 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

Operating environment

temperature: +10 to +35 ℃, humidity: 30 to 80 %RH (non-condensing)
positioned away from sources of electrical noise and vibration

1) Optional measuring probe is required
2) Accuracy is the repeatability in terms of standard deviation based on the manufacturer’s calibration weights
