Surface Interfacial Tensiometer Platinum ring method BZY-B (BZY102)
General introduction:
The surface tension is basic principle of determining the solubility, wetting, bubbling, coating, permeability and some other properties of a liquid.
Feature:
Compared with other surface tensiometer, BYZR serial surface tensiometer includes but is not limited by the following advantages:
Automatic measuring, by which the may included error can be decreased
The equilibrium value of surface tension can be read automatically
Absolute exact one key resetting
One-key calibrating can be realized with attached standard weight rapidly and exactly
It fully complies with the basic principle of Willhelmy Plate method and can actualize the measuration in the following cases:
Surface tension varies in different time because of the existence of an surface active agent
To measure some high viscosity liquid (the equilibrium value can be read automatically)
To measure the tension on an interface between two different liquids that one can not dissolved in the other one, such as oil and water
The sensor can respond dater for carrying with high accuracy, and thus it becomes possible to supply reference dater for carrying out a favorable reproducibility.
Operating simple without being controlled by any external computer
The deviation of the instrument is very low because of it own structure which ensure that the errors measuring can be controlled effectively
A constant-temperature sample cup, a sample thermometer and an external constant-temperature tank can be optional equipped to the tensiometer.
