表面张力仪WilhelmyplateandDuNoüyringtensiometerOverview-Principle表面张力仪TensioCADisatensiometerbasedontheprincipleofmeasuringaforceagainstadisplacement
表面张力仪TensioCAD is a tensiometer based on the principle of measuring a force against a displacement. This method, often called force tensiometry or Wilhelmy method, consists in diving a platinium plate of perimeter L in a liquid having a superficial tension σ. Platinium plate is then lift and, with the help of a balance, the capillary force F exerted on the plate is measured.
表面张力仪原理
Equiped with a high precision weighing cell and coupled to a user-friendly and full software, TensioCAD is a tensiometer which helps you in numerous type of applications and measurements. TensioCAD offers 3 types of measurements: Wilhelmy plate, Du Noüy ring or Washburn method.
