SYD-6541A Fully automatic interface tension testerDetailed product description：

1、 Purpose:
The SYD-6564A fully automatic interfacial tension tester is designed and manufactured in accordance with the requirements of the national standard GB/T6541 "Petroleum Product Oil Water Interface Tension Determination Method (Circular Ring Method)". It is suitable for measuring the interfacial tension between mineral oil and water under non-equilibrium conditions (liquid-liquid phase interface), and can also measure the surface tension of various liquids (liquid-liquid gas phase interface).

The SYD-6564A fully automatic interface tension tester adopts a large screen dot matrix LCD display, with unmarked buttons for full Chinese character menu prompts. It has a high degree of automation, reliable operation, good repeatability, and simple operation. Simply press the menu prompts after turning on the machine to complete all tests. This instrument has automatic temperature compensation, clock control, power-off storage, printing, and automatic average value calculation; The RS232 interface with redundant design can achieve communication and online operation with computers, and can also directly transmit test results to handheld computers for analysis and other functions. It is currently an ideal instrument for measuring the interfacial tension between oil and water in petroleum products in China.
