1. The Wen bridge sine wave oscillator composed of high-precision and high-speed operational amplifiers has the characteristics of low distortion and easy debugging. Under non-equilibrium conditions, measuring the interfacial tension of various liquid gas and liquid-liquid phases is easy to operate, stable and reliable, and automatically calculates the tension value. It can be used for determining the interfacial tension of products such as petroleum, chemical, power, pharmaceutical liquids, etc.

2. Adopting a newly improved magnetic can enclosed electromagnetic force balance sensor, the response speed and linearity have been improved; The new sensor only needs to be calibrated at one point, solving the problem of the previous generation of sensors requiring multi-point calibration to ensure linearity and accuracy.

3. The internal microprocessor of the instrument can also perform bidirectional compensation based on the working temperature, with a reference temperature of 25 ℃, and the compensation range can meet the environmental temperature of all laboratories.
