1. The two test methods of platinum plate and platinum ring are used together;
2. When the platinum plate is tested, the displayed value is the surface tension value;
3. When using the platinum ring test method, the displayed value automatically locks the maximum force value of the sample, and then calculates the surface/interfacial tension value through the attached calculation software or selects the data processing software to automatically calculate by the computer;
4. Platinum ring size: the wire radius is 0.185mm, the ring radius is 9.55mm, and the ring circumference is 60mm;
5. When using the platinum ring test method, it fully complies with the following domestic and international standards:
GB/T 22237-2008 Determination of Surface Tension of Surfactants

6. Fully automatic measurement to avoid human error;
7. Full-scale automatic calibration, accurate and reliable data, excellent repeatability;
8. One-key clearing of the full range, complete in an instant, the zero position is stable and no drift;
9. Adopt international advanced lifting platform drive technology, no vibration and noise;
10. The structure of the instrument is reasonable, it can work completely independently, and a computer can also be selected for data processing;
11. When using the platinum plate, the surface tension or interfacial tension of the liquid can be measured in real time. It is very practical for measuring samples containing surfactants or volatile substances whose surface tension will change with time (select data processing software). , the test curve can be displayed in real time, and the details of the tension change can be obtained);
12. It can automatically test the surface tension of medium and high viscosity liquid samples when using the platinum plate test;
13. Both test methods can measure the interfacial tension between immiscible liquids such as: oil/water interface;
14. Standard data processing software: It can automatically collect test data, display the test curve in real time, and the curve can be automatically enlarged, accessed and printed. It can compare multiple curves, and the original data can be converted into Excel files, which can automatically calculate the surface tension value when using the platinum ring test method;
15. Standard accuracy calibration function: using twice distilled water and pure ethanol as the standard, the overall test error of the instrument is automatically calibrated, which can ensure that the instrument is in the accurate state of the factory for a long time;
16. Standard temperature automatic compensation function: using twice distilled water and pure ethanol as the standard, automatically summarize the samples at different temperatures to the test value at 20 °C; 17. With a variety of temperature control options to meet different test requirements; 18. Meet the special requirements of users and undertake non-standard products.
