Features
1. Platinum ring test principle;
2. Manually control sample stage lift;
3. Automatic peak hold;
4. Clear the whole range, complete with one key, return to zero momentarily, zero position is stable without drift;
5. Full-range automatic calibration data is accurate and reliable, with excellent repeatability;
6. The displayed value is the force value of the sample, which must be converted into surface tension (freely provided by the calculation software) or optional data processing software to be automatically calculated by the calculation software;
7. Can accurately test the interfacial tension of different liquids, such as the oil/water interface;
8. The platinum ring wire has a radius of 0.185mm, a ring radius of 9.55mm, and a ring circumference of 60mm.
9. Full compliance with domestic and international standards:
10. The instrument has a reasonable structure and works independently, without any additional equipment (such as an external computer, etc.);
11. Test data can be output through RS232C
12. Can completely replace pointer type mechanical surface tension meter
13. In addition to manual control of the sample platform lift, this series of instruments, the main structure and technical parameters and QBZY series similar, with high quality design, economical price, high cost performance Technical Parameters:
