Force Tensiometer model K20

The K20 Force Tensiometer is a semi-automatic instrument for precise surface and interfacial tension measurements. Using the Du Noüy ring or Wilhelmy plate methods, it provides highly accurate tensiometric data. It can also measure liquid density via probe buoyancy. With pre-configurable parameters, the K20 supports fully independent, standalone operation without requiring a computer.

  • Semi-automatic instrument, manual sample stage setup and a motorized stage driven by pre-set measurement programs
  • Surface tension (SFT) and interfacial tension (IFT) measurement
  • Using the Du Noüy ring or Wilhelmy plate methods
  • Able to measure density and temperature of liquid sample

Description

Features

  • Surface Tension (SFT) and Interfacial Tension (IFT) of liquid sample
  • The measurement is using either Du Noüy ring tear-off or Wilhelmy plate methods
  • The liquid density determined using the buoyancy of an immersed probe
  • The measurement range is 1 to 999 mN/m with the highest resolution of 0.01 mN/m 
  • The stage travel distance is 90 mm
  • Temperature control (options) ranges from -10 to 130 °C
  • A manual sample stage setup alongside a motorized stage driven by pre-set measurement programs
  • Various applications such as checking the degradation status of transformer and insulating oils by measuring interfacial tension according to ASTM D 971 and IEC 62961 standards
  • Validating tank clearance and detecting cleaning agent residues in the food industry
  • Determining the effectiveness of wetting agents and monitoring surfactant content below the critical micelle concentration (CMC)
  • Measuring interfacial tension to assure quality and optimize emulsifiers
  • Manufacturer: KRÜSS, Germany.
