BZY-1Fully automatic surface tension meterReferring to the advantages of existing similar instruments at home and abroad, the original BZY series automatic surface tension meter has been comprehensively upgraded and improved, adopting multiple new technologies, which has brought the technical level and performance of domestic fully automatic surface/interface tension meters to a new height. The main improvements include:
① Adopting sensor technology for higher accuracy, better repeatability, and stability;
② When using the platinum ring testing method, the peak automatic holding function has been added for ease of use;
③ We have successfully developed our company's unique accuracy automatic calibration function, which calibrates the overall testing accuracy of the instrument using distilled water and ethanol, ensuring that the instrument remains in the precise state at the time of leaving the factory for a long time;
④ We have successfully developed our company's unique temperature automatic compensation function, which enables users to uniformly correct their measurement data at different temperatures to the testing state at 20 ℃;
⑤ The control and processing programs of the instrument hardware have been enhanced and optimized, resulting in superior performance;
⑥ Successfully developedFully automatic surface tension meter/The data processing software for the interface tension meter can automatically collect test data, display test curves in real time, and automatically enlarge, access, and print the curves. Capable of comparing multiple curves, converting raw data into Excel files, and automatically calculating surface tension values when using platinum ring testing methods;
⑦ Adopting lifting platform drive technology, there is no vibration or noise
BZY-1Main features:
1. Platinum plate, platinum gold ring, and platinum stirrup are used for testing;
When testing platinum plates, the displayed value is the surface tension value;
When using the platinum ring testing method, the displayed value automatically locks the maximum force value of the sample, and then the surface tension value is calculated using the provided calculation software or automatically calculated by the computer using data processing software;
4. Platinum ring size: wire radius of 0.185mm, ring radius of 9.55mm, ring circumference of 60mm;
When using the platinum ring testing method, it fully complies with the following domestic and international standards:
GB/T 22237-2008 Surface active agents Determination of surface tension
JB/T 9388-2002 Technical Conditions for Interface Tension Tester
JB/T 18396-2001 Natural Latex Determination of Surface Tension by Ring Method
SH/T 1156-95 Synthetic Latex Surface Tension Determination Method
GB/T 6541-86 Petroleum products Determination of interfacial tension between oil and water (ring method)
ISO 1409:1995 Determination of surface tension of plastics, rubber, polymer dispersions and latex
ISO 6295-1983 Petroleum products - Determination of interfacial tension between mineral oils and water (ring method)
GB/T 5549 (ISO304-1985) Determination of surface tension by pulling film method
And standards such as ISO14090-82, ASTM D1417, EN14370, ZB2025-93, GB2960-82, GB6541-86, etc
6. Fully automatic measurement to avoid human operation errors;
7. Full range automatic calibration, accurate and reliable data, excellent repeatability;
8. One click reset, instant completion, stable zero position without drift;
9. Adopting lifting platform drive technology, there is no vibration or noise;
10. The instrument has a reasonable structure, works independently, does not require any additional equipment (such as an external computer, etc.), and can also be optionally equipped with a computer for data processing;
11. When using platinum plates, the surface tension or interfacial tension of liquids can be measured in real time. It is very practical for measuring samples containing surfactants or volatile substances whose surface tension changes over time (using data processing software can display the test curve in real time and obtain detailed information on tension changes);
When using a platinum plate for testing, it can automatically measure the surface tension of medium and high viscosity liquid samples;
Both testing methods can measure the interfacial tension between immiscible liquids, such as the oil/water interface;
14. Data processing software (optional): It can automatically collect test data, display test curves in real time, and the curves can be automatically enlarged, accessed, and printed. Capable of comparing multiple curves, converting raw data into Excel files, and automatically calculating surface tension values when using platinum ring testing methods;
15. Accuracy calibration function (optional): Using twice distilled water and pure ethanol as standards, the overall testing error of the instrument is automatically calibrated to ensure that the instrument is in the accurate state at the time of leaving the factory for a long time;
16. Automatic temperature compensation function (optional): Using twice distilled water and pure ethanol as standards, automatically summarize the test values of samples at different temperatures to 20 ℃;
17. USB data interface output, convenient for connecting with laptops;

18. Comes with multiple temperature control options to meet different testing requirements;

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