Interface Tension Tester

The intermolecular force forms the interface tension or surface tension of the liquid. The value of the tension can reflect the physical and chemical properties of the liquid and its material composition, which is one of the important indicators for the related industries to inspect the product quality. This product is designed based on  the DuNouy Ring method, the surface tension (liquid-gas interface) and liquid interface tension (liquid-liquid interface) of various liquids are measured. This method is widely used because of its simple operation and high accuracy. Widely used in power, petroleum, chemical, pharmaceutical, food, teaching and other industries.

• This instrument is a Wien bridge sine wave oscillator composed of high-precision and high-speed operational amplifiers, characterized by low distortion and easy debugging.

• The instrument is easy to operate and works stably and reliably. Under non-equilibrium conditions, it can measure the surface tension of various liquid-gas phases and the interfacial tension of liquid-liquid phases, and automatically calculate the tension value.

• The instrument adopts a newly improved magnetic tank sealed electromagnetic force balance sensor, which improves response speed and linearity.

• The new sensor only needs to be calibrated at one point, solving the problem of multiple-point calibration required by the previous generation sensor to ensure linearity and accuracy.

• The internal microprocessor of the instrument can also perform bi-directional compensation based on the working temperature, with 25℃ as the reference, providing compensation range that can meet the environmental temperature requirements of all laboratories.
