As we all know, the surface tension is to determine the liquid nature principles of solubility , wetting, bubbling, coating and permeability. People often analysis surface tension of a given liquid , and then study the physical representation compared to other liquids or solids. This study is the basic means of quality control in the process of industrialization.
BZY-1 series of Automatic surface tension meter It provides a perfect solution for customers on the surface tension . It is the perfect ‘linear’, fully able to detect changes due to existence of solution time changes or surfactant. Moreover, the scope of its application will be more widely used due to users’ reasonable and smart use.

Instrument features:Compared with other surface tension meter, BZY series of surface tension meter including but not limited to the following advantages:

² Automatic measurement,reduce human error to a minimum；
² Automatic reading of surface tension balance value；
² One key to reset(any numberbetween0－400mN),absolutely correct；
² One key to calibrate,with standard weights attached,rapidly and accurately；
² The platinum plate method,fully comply with the requirement of basic principle of Wilhelmy platinum plate , so as to provide possibility of measuring under the following environment:
l Changes of surface tension due to the presence of surfactants value
l The measurement of high viscosity liquids (automatically read balance value)
l Interfacial tension is not dissolved between two kinds of liquid, such as oil and water.
² Sensor has sensitive response, high accuracy, in order to provide possibility of excellent repeatability and comparability of data .
² Simple operation,without the need for any external computer control
² small machine error, more effective control of all kinds of errors in testing process
² sample temperature cup , sample temperature detection device and the external thermostatic bath can be chosen
