surface tension
precision tensiometer
Determines the force needed for the ring to break the surface. The force needed for the ring to break the surface (overcome the surface tension) is determined. This measurement is in dynes/centimeter.
interfacial tensiometer
This instrument pulls the ring through the boundary between a lower, higher density liquid and the liquid floating above. It can also measure the force needed to break the boundary going from the floating liquid to the greater density liquid.
automatic tensiometer
The DST 60 Auto Tensiometer runs liquid surface tension measurement tests with either duNouy Rings or Wilhelmy Plates. The test results are displayed on the instrument and can also be sent to a printer or computer. After loading the sample the test process is automatic.
Digital Tensiometer
An easy to use Tensiometer for both duNouy Ring Method and Wilhelmy Plate Tests. The CSC Digital Tensiometer eliminates the need for the DuNouy ring correction. The test results are presented digitally in actual surface tension.
