Model: BZY-A （platinum plate method）
Product name: Automatic surface/interface tensiometer
Product name: Automatic surface/interface tensiometer
Brief introduction
BZY series automatic surface tensiometer, made up of high precise and stable force measurement system, microcomputer control system, platinum plate （ring） measurement device, is compact in design, simple and reliable in structure, easy in operation （automatic/manual）. It features net weight in whole range （one-key minimum clearing）, whole range automatic calibration, good repeatability, accurate and reliable test result as well as liquid crystal display of test data with S232C output interface. BZY series is stable in performance and easy in operation. Its high-performance, economical and cost effective characteristics make it applicable to research and development and quality control in industrial and mining establishments as well as scientific research or teaching in universities and colleges. Our Company holds fully independent inlectual property of produced instruments, ensuring safe and long-term service.
Ex-factory price: RMB 9800
Reference strike price: RMB 7350 - 8800
Main features:
1. The platinum plate test principle enables the operation easy;
2. Fully automatic measurement can avoid the manual operation error;
3. Whole range minimum clearing: one-key minimum clearing in a flash; stable and non-drifting zero position;
4. Automatic calibration in whole range ensures accurate and reliable data and good repeatability;
5. The display value is sample surface tension without re-calculation;
6. The instrument is reasonable in structure and independent in operation, without any attached equipment （such as external computer, etc）;
7. The measurement of surface tension can be achieved, and the surface tension varies at different time （especially those containing surface active agent or volatile substance）
8. Balance result can be got in automatic measurement of surface tension of medium and high viscosity liquid samples;
9. It can measure the interfacial tension of non-mixed liquid such as oil/water interface
10. It can totally replace traditional mechanical surface tensiometer;
11. Besides the manual control of sample stage raising, the main structure and technical parameters is similar to that of QBZY, with high quality, economical and cost effective characteristics.
