Jyw-200a microcontroller automatic surface/interface tensiometer
Micro - controlled automatic surface and interface tensimeter, which conforms to JB/T9388 and ISO1409 standard, is a kind of instrument for testing liquid surface and interface tension by physical method.
The surface and interface tensimeter adopts microcontroller technology, which is simple and intelligent.
Automatic zero, real-time display force value and curve, peak holding and other functions;
The experimental results are automatically corrected and automatically averaged;
The results can be easily displayed, stored and printed.
To test the interfacial tension value of electric oil in the electricity and water sector to strengthen the supervision over insulating oil quality.
The surface tension value of various liquids can be tested in oil, chemical, scientific research and other departments to enhance the analysis of various liquids.
Main technical parameters of surface and interface tensimeter:
1. Measuring range: 0 -- 200.0mN/m
2. Resolution: 0.01mN/m
3. Measurement method: ring method
4. Relative error of the display value: < / -1%
5. Power supply: 220V 50H
6. Main frame size: 300 x 300 x 400
Characteristics of surface and interface tensiometer instruments:
1. With microcomputer control, the real-time force value change curve can be displayed, which can be used to analyze the changes of the interface or surface property of the liquid during the stretching process of the platinum ring.
The curve is saved in the form of pictures and can be printed together with the test report. It can also be copied and printed independently.
2. Easy to test, easy to save test data and print test report.
The test data is saved to the software in the way of database. Each test can be saved for a long time, and the average result is obtained by the average test of the unified liquid.
3, PC and instruments through the serial port communication, simple connection, don't need a data acquisition card, do not need to change the PC hardware, the system requirements is low, as long as there is a serial interface to be able to run more than the Windows xp system of microcomputer can be used.
4. The instrument and software are controlled in two directions, and the instrument can work independently.
