Features: 1. Platinum plate test principle, simple and convenient operation; 2. Automatic digital measurement reduces human error; 3. Full-range clearing: One-key clear, instant completion, no zero temperature drift; 4. Full-range auto-calibration: The data is accurate, reliable, and reproducible; 5. The displayed value is the surface tension value of the sample and no need to calculate again; 6. The instrument is compact and works independently without any additional equipment (such as an external computer); 7. Ability to measure changes in the surface tension of a specimen as a function of time (especially when there is a surfactant or contains a volatile material); 8. Automatically measure medium and high viscosity liquid samples and obtain a balanced result; 9. Measurable interfacial tension between immiscible liquids such as: oil/water interface; 10. Can completely replace the traditional mechanical surface tension meter; 11. In addition to manual control of sample platform lift, this series of instruments is similar to the QBZY series in terms of its main structure and technical parameters. It has high quality design, economical price, and high cost performance. Technical Parameters: Test Mode: Platinum Plate Method Operation method: Manually lift the sample table, automatic measurement Test Range: 0-600mN/m Sensitivity: 0.1 mN/m Measurement Accuracy: ±0.1 mN/m (2 Distilled Water at 20°C, Error in Reference Value) Repeatability: ±0.1 mN/m (2 distilled water at 20°C, deviation from literature values) Data display: Wide viewing angle backlit LCD display Sample temperature range: 0～100°C (Need constant temperature bath and constant temperature bath) Measurement time: 3-5 seconds to measure low concentration sample solution Container constant: at least 15ml Data output: RS 232C serial port or optional USB data interface Power Supply: AC220V, 1A
