4.Character
Using a 4.3-inch touch screen, all operations and information are completed or displayed on the screen.
It can be used to measure the surface interfacial tension of liquids.
Simple and fast operation.
Automatic measurement with high repeatability can be achieved for the set measurement conditions.
One such product is the BZY100 & BZY200 surface tensiometers, which are widely used in quality
control processes related to surface interfacial tension, such as emulsifier or wetting agent and cleaning agent testing . It is reliable, easy to use, independent of computers and other equipment, and can provide accurate and reliable analysis when testing a large number of samples. BZY100 & BZY200 are controlled by automatic motor to realize fast switching of accurate surface tension measurement.

6. Quick measurement preparation
The open sample area is spacious and equipped with a smooth and precise sample stage, which is very convenient for measurement preparation during use . The equipped magnetic lock air shield prevents disturbed airflow during measurement from affecting the measurement.Smart measurement routines supported by the processor:
The built-in measurement program can control the motorized sample stage, ensuring that the measurement process is free of human interference and can be accurately repeated . The sample stage is automatically raised and lowered, and other measurable measurement parameters can also be adjusted as needed .

8. Operates without an external PC
BZY100 & BZY200 surface tensiometers use two measurement methods and built-in data memory, so they can be used independently to meet the needs of various purposes. The instrument is lightweight, easy to install, and can be moved quickly.
Extensive data management options
In addition to displaying the results directly on the 4.3-inch touch screen, the BZY100 & BZY200 also provide a wealth of data management options, equipped with easy-to-manage large-space data storage for quick access to all results. In addition, the measured data, together with all important
parameters, can be printed out.
