Product Features:

The instrument utilizes a Wien-bridge sine-wave oscillator constructed with high-precision, high-speed operational amplifiers, offering low distortion and ease of adjustment. It supports bilingual operation (Chinese and English). It measures (surface) and interfacial tension for various liquid-gas and liquid-liquid systems under non-equilibrium conditions. The instrument is simple to operate, stable, and reliable, automatically calculating tension values; it is suitable for measuring the (surface) and interfacial tension of products in the petroleum, chemical, electric power, and pharmaceutical industries.

It employs a newly improved, enclosed electromagnetic force balance sensor (magnetic pot type), which enhances response speed and linearity. The new sensor requires only single-point calibration, resolving the multi-point calibration requirement of previous generations needed to ensure linearity and accuracy.

The internal microprocessor performs bidirectional compensation based on the operating temperature (using 25°C as the reference), with a compensation range capable of accommodating the ambient temperatures of any laboratory environment. Technical Specifications:
