Surface Tension Measuring Instrument

Surface Tension Measuring Instrument

When using the platinum loop test method, the display value automatically locks the maximum strength value of the sample, and then calculates the surface/interfacial tension value through the attached calculation software or selects the data processing software to calculate automatically by the computer

Product Details

Main features of surface tension measuring instrument

1. Use both platinum plate and platinum ring test methods;

2. When platinum plate is tested, the display value is the surface tension value;

3. When using the platinum loop test method, the display value automatically locks the maximum strength value of the sample, and then calculates the surface/interfacial tension value through the attached calculation software or selects the data processing software to calculate automatically 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. Determination of interfacial tension between petroleum product oil and water (ring method)

ISO 6295-1983 "determination of interfacial tension between petroleum products, mineral lubricating oils and water - ring method"

JB/T 9388-1997 interface tensiometer technical conditions

Iso1409:1995 - determination of surface tension of plastics, rubber, polymer dispersions and latex

Test method for surface tension of synthetic latex

ISO 304-1985 "determination of surface tension by pulled liquid film method for surfactants"

ISO 4311-1979 requirements for standards such as "methods for the determination of surface tension in anionic and non-ionic surfactant rings".

6. Automatic measurement to avoid manual error;

7. Full range automatic correction, accurate and reliable data, excellent repeatability;

8. One-key reset for full range, instant completion, stable zero position without drift;

9. Adopt international advanced lifting platform driving technology, without vibration and noise;

10. The instrument is of reasonable structure and works independently. No additional equipment (such as external computer) is required.

11. When using a platinum plate, can real-time measuring liquid surface tension and interfacial tension, for measuring containing surfactant or volatile substances, its surface tension will change with different time of the sample, very practical, choose data processing software, can be real-time display test curve, get tension change details).

12. The platinum plate can automatically test the surface tension of medium and high viscosity liquid samples;

13. The interfacial tension between immiscible liquids can be measured in both test methods, such as oil/water interface;

14. Data processing software (optional) : it can automatically collect test data, display test curve in real time, and automatically enlarge, access and print the curve.Can carry out multiple curve comparison, the original data can be converted into Excel file, can automatically calculate the platinum ring test method when the surface tension value;

15. Special accuracy calibration function (option) : with 2 times of distilled water and pure ethanol as the standard substance, the overall test error of the instrument is automatically calibrated to ensure that the instrument is in the accurate state when leaving the factory for a long time;

16. Characteristic of the automatic temperature compensation function (option) : is a standard with 2 times distilled water and pure ethanol content, automatically to the unity of the samples under different temperature induction to 20 ℃ when test values;

17. With a variety of temperature control options, to meet different test requirements;
