11 470,00 

A versatile force tensiometer

Kibron EZ-PI Plus was designed and built with reliability and ease of use in mind. EZ-PI Plus is compact size, and easy to move. State-of-the-art sensor technology with excellent resolution, connection for water bath, and intuitive user interface.

Accurate and fast surface and interfacial tension measurements

  • A high precision instrument for research
  • Surface tension, oil/water interfacial tension, and contact angle measurements
  • Measures samples with high viscosity (Wilhelmy technique combined with small diameter probe). Currently tested to 100 000 mPas (Newtonian),
  • An easy to use tensiometer for educational purposes, no special training needed
  • An ideal instrument for the metal plating industry
  • Excellent for oil refineries for the monitoring of sour water
  • ASTM D 1331 – 14

Contact angle measurements

  • Advancing and receding contact angle
  • Wetting measurements of single fibers, for example textile, hair and reinforcement fibers down to 1 µm diameter
  • Connects to water bath for temperature control
