Professional Automatic Surface Interfacial Tensiometer Platinum plate method BZY-A (BZY-101)
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:
1. automatic measuring, by which the may included error can be decreased
2. the equilibrium value of surface tension can be read automatically
3. absolute exact one –key resetting
4. One-key calibrating can be realized with attached standard weight rapidly and exactly
5. It fully complies with the basic principle of Willhelmy Plate method and can actualize the measuration in the following cases:
6. Surface tension varies in different time because of the existence of an surface active agent
7. to measure some high viscosity liquid ( the equilibrium value can be read automatically)
8. 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
9. 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.
10. operating simple without being controlled by any external computer
11. the deviation of the instrument is very low because of it own structure which ensure that the errors I measuring can be controlled effectively
12. a constant-temperature sample cup, a sample thermometer and an external constant-temperature tank can be optional equipped to the tensiometer.
