Overview
The FANGRUI QBZY-3 surface tensiometer is a professional-grade interface chemical analysis instrument designed to meet users' needs for High Accuracy R & D and quality control. Surface tension is the basic element that determines the properties of liquid solubility, wettability, foaming, etc. The instrument can study its physical performance through the analysis of liquid surface tension. It is the basic means of quality control in the industrialization process. This model has been awarded a national patent (patent number: 2011200652242).
Features
1. Both platinum plate and platinum ring test methods are used (platinum ring method needs to be purchased separately).
2. Automatic measurement, platinum plate test, the display value is the surface tension value.
3. When using the platinum ring test method, the display value automatically locks the maximum force value of the sample, and calculates the surface tension value through the calculation software.
4. Fully automatic measurement to avoid human error.
5. Full scale automatic correction, accurate and reliable data, excellent repeability.
6. One-click zero, instant completion, zero stable without drift.
7. Adopt international professional lifting platform drive technology, with no vibration or noise.
8. The instrument has a reasonable structure and works independently without any additional equipment (such as an external computer, etc.). It can also be equipped with a computer for data processing.
9. When using platinum plate, it can measure the surface tension of the liquid in real time, which is very practical for measuring the surface tension of the sample that changes over time.
10. When using platinum plate test, it can automatically test the surface tension of medium and high viscosity liquid samples.
11. Both test methods can measure the interfacial tension between dissimilar mixed liquids such as oil/water interface.
12. The data processing software can automatically collect and test Linear dispersion, Linear dispersion can be enlarged, accessed, printed, can compare multiple test Linear dispersion, and can automatically calculate the surface tension value of the platinum ring method.
13. With accuracy correction function, with 2 distillation water and pure ethanol as the standard, the overall test error of the instrument is automatically calibrated.
14. Equipped with automatic temperature compensation function, the test value of the sample at different temperatures is automatically summarized to the test value at 20 ° C.
15. Comes with a variety of temperature control options to meet different test requirements.
Principle
The FANGRUI QBZY-3 surface tensiometer uses the platinum plate method and the platinum ring method for measurement. Under the platinum plate method, the instrument immerses the platinum plate in the liquid through the automatic lifting platform, measures the tensile force of the liquid on the plate, and directly calculates and displays the surface tension value. Under the platinum ring method, the instrument measures the maximum tensile force when the platinum ring is separated from the liquid surface, and calculates the surface tension value through the included calculation software or data processing software. The instrument ensures the accuracy and repeability of the measurement through fully automatic operation, full scale correction and temperature compensation.
Applications
