LDZL-I Automatic oil interface tension tester is a high-precision instrument based on the ring method (platinum ring method), which is widely used in power, petroleum, chemical, pharmaceutical, food and teaching industries, and is used to measure the surface tension (liquid-gas interface) and interfacial tension (liquid-liquid interface) of various liquids. The instrument uses an original fast-response electromagnetic force balance sensor to improve the measurement accuracy and linearity. Only one point needs to be calibrated to complete the instrument calibration, and the operation is simple and fast.

High-precision measurement: It has extremely high measurement accuracy, with an accuracy of 0.1% reading ±0.1 mN/m, and a resolution and sensitivity of 0.1mN/m, ensuring the accuracy of the measurement results.
Intelligent calibration and compensation: The instrument supports pure water calibration, and the accuracy of the instrument is tested by testing the surface tension of pure water. At the same time, the integrated temperature detection circuit can automatically compensate the test results for temperature and eliminate the influence of ambient temperature on the measurement results.
Intuitive and easy-to-use interface: Equipped with a 240×128 dot matrix LCD display and unmarked buttons, the menu design is simple and clear, and supports screen protection function. The instrument can store up to 255 historical records with time stamps, which is convenient for users to check and trace at any time.
Multi-function output and connection: Built-in high-speed thermal micro printer, supports offline printing, and the printing effect is beautiful and fast. At the same time, it provides a standard RC232 interface, which can be connected to a computer to facilitate the processing of test data and meet the diverse needs of users.
Stable and reliable performance: The instrument uses high-quality materials and advanced manufacturing processes to ensure long-term stable operation. It has a wide measurement range and is suitable for tension testing of various liquids. At the same time, the instrument has good anti-interference ability and can maintain the accuracy of measurement results in complex environments.
