Features
1. A platinum plate testing principle, operation simple and convenient;
2. Automatic digital measurement to reduce artificial operation error;
3. The full range of reset: a key reset, instantaneous, zero temperature without drift;
4. Full range automatic correction: data accurate and reliable, repeatability is wonderful;
5. Display value is the value, the surface tension of the sample don't need to calculate again;
6. The instrument structure is compact, work independently, without any additional equipment (such as an external computer, etc.);
7. To measure the surface tension of the specimen with different time changes (especially a surfactant or containing volatile substances);
8. Automatic measurement, high viscosity liquid samples and get the equilibrium results;
9. Measurable don't mix liquid interfacial tension between such as: oil/water interface;
10. Can completely replace the traditional mechanical surface tensiometer;
11. This series of instruments in addition to manual control sample platform lift, main structure and technical parameters and QBZY series, high quality design, economical price, high cost performance
