The intermolecular forces create the surface tension or interfacial tension of liquids. The magnitude of the tension value can reflect the physicochemical properties and material composition of the liquid, making it one of the important indicators for assessing product quality in relevant industries. Our company produces fully automatic tensiometers that comply with the GB/T6541 standard, based on the ring method (platinum ring method), to measure the surface tension of various liquids (liquid-gas interface) and the interfacial tension between liquids (liquid-liquid interface). This method is widely used due to its simplicity and high precision. It is extensively utilized in power, petroleum, chemical, pharmaceutical, food, education, and other industries.

Adopting an innovative fast-response electromagnetic force balance sensor, it improves measurement accuracy and linearity;

The instrument calibration requires only a single-point calibration, solving the issue of needing multiple points for calibration in the previous generation of sensors. It eliminates the need for zero adjustment potentiometers and full-scale adjustment potentiometers;

Real-time display of equivalent tension values and current weight (can be used as an electronic balance for weighing);

Integrated temperature detection circuitry provides automatic temperature compensation for test results;

A 240×128 dot matrix LCD screen with non-marked buttons and screen protection features;

Time-stamped historical records, capable of storing up to 255 entries;

Built-in high-speed thermal micro-printer for beautiful and quick printing, featuring offline printing capability;

Equipped with a standard RC232 interface that can connect to a computer for easy data processing (optional).
