Quality Manager

The Tensiometer K11 - ideal for measurement for surface tension and interfacial tension - combines easy handling with flexible application.

The large well-illuminated sample chamber can be opened wide and facilitates the exchange of sample liquid and measuring devices. The measuring data are shown on an easily readable tensiometer display and can either be printed or transferred to a PC.

Features of the Tensiometer K11

  • Precise and robust force-measuring system for interfacial tension and surface tension
  • Ideal for solving routine tasks
  • Liquid density measurement
  • Fully automatic surface tension and interfacial tension measurement of liquids
  • Storage of measuring parameters
  • Software for data management

Application

  • Quality control for measuring surface-active agent concentration
