The instrument operates using a precision torsion wire, sensor, platinum ring, and motorized lifting mechanism. When the platinum ring is immersed in the test liquid and the container descends, the liquid film stretches, applying downward force to the ring. This force twists the torsion wire, and the sensor measures the displacement, converting it to voltage that is processed and displayed as the tension value. The maximum value before film breakage is recorded as the measured tension.
This ISO1409 certified instrument provides laboratory-grade accuracy with 0.01 mN/m resolution and ±1% relative error, making it ideal for research and quality control applications requiring precise surface tension measurements.
