Both platinum plate and platinum ring test methods are used together, fully automatic measurement, full range one-key reset, full range automatic calibration, automatic accuracy correction, and automatic temperature compensation. Sample temperature control, multi-function data processing software. The instrument has accurate measurement, excellent repeatability, professional technology and excellent performance.

Advantages

① Using international professional sensor technology, it has higher precision, better repeatability and better stability;  

② When using the platinum ring test method, the peak value automatic hold function is added to eliminate human error and the measured value is more accurate;  

③ Successfully developed the company's unique accuracy automatic calibration function, using distilled water and ethanol to calibrate the overall test accuracy of the instrument, which can ensure that the instrument is in the accurate state when it leaves the factory for a long time;  

④ Successfully developed the company's unique temperature automatic compensation function, so that the user's measurement data at different temperatures can be uniformly corrected to the test state at 20°C;  

⑤ The control and processing procedures of the hardware part of the instrument have been enhanced and optimized, and the performance is superior;  

⑥ Successfully developed the data processing software for the automatic Surface Tensiometer/interfacial tensiometer: it can automatically collect test data, display the test curve in real time, and the curve can be automatically enlarged, stored and printed. Can compare multiple curves, the original data can be converted into an Excel file, and can automatically calculate the surface tension value when using the platinum ring test method; 

⑦ Adopt international professional lifting platform drive technology, no vibration and noise 

main feature

1. Platinum plate method;  

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 included calculation software or selects the data processing software to be automatically calculated 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 (CN) and international standards:  

GB/T 22237-2008 Determination of Surface Tension of Surfactants  

JB/T 9388 -2002 Technical Conditions for Interfacial Tensiometer  

JB/T 18396-2001 Determination of surface tension by natural latex ring method

6. Fully automatic measurement to avoid human error; 

7. Full-scale automatic calibration, accurate and reliable data, excellent repeatability; 

8. One-button zero reset of the full range, which is completed instantly, and the zero position is stable without drift; 

9. Adopt international professional lifting platform drive technology, no vibration and noise; 

10. The instrument has a reasonable structure and works independently without any additional equipment (such as an external computer, etc.), and can also be equipped with a computer for data processing; 

11. When using a platinum plate, it can measure the surface tension or interfacial tension of the liquid 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. When using platinum plate to test, it can automatically test the surface tension of medium and high viscosity liquid samples; 

13. The two test methods can measure the interfacial tension between immiscible liquids such as: oil/water interface;     

14. Data processing software (option): It can automatically collect test data, display test curves in real time, and the curves can be automatically enlarged, stored and printed. Can compare multiple curves, the original data can be converted into an Excel file, and can automatically calculate the surface tension value when using the platinum ring test method;  

15. Accuracy calibration function (option): With 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 when it leaves the factory for a long time;  

16. Automatic temperature compensation function (option): with twice distilled water and pure ethanol as the standard, it automatically summarizes the test values at 20°C for samples at different temperatures;   

17. A variety of temperature control options are attached to meet different test requirements;  

18. Meet the special requirements of users and undertake non-standard products.
