Instrument Overview Technical Parameters Performance characteristics
This instrument uses a high precision and high speed operational amplifier to form a Vinci bridge sine wave oscillator, which has the characteristics of low distortion and easy debugging. Under non-equilibrium conditions, the (surface) interface tension of various liquid – gas and liquid – liquid phases is measured. The operation is simple, the work is stable and reliable, and the tension value is automatically calculated. It can be used to determine the (surface) interface tension of petroleum, chemical, electric power, pharmaceutical liquids and other products. The instrument uses a completely new improved magnetic tank closed electromagnetic force balance sensor, improving response speed and linearity; The new sensor only needs to be calibrated at one point, solving the problem that the previous generation of sensors needed multi-point calibration to ensure linearity and accuracy. The instrument's internal microprocessors can also perform two-way compensation based on operating temperature at 25 ° C, with a compensation range capable of meeting the ambient temperature of all laboratories

1. LCD display, Chinese prompt menu operation, automatic lifting, good stability.
2. With 25 ° C automatic temperature compensation function, the effect of temperature on the measured tension value is solved.
3. The instrument automatically zeros, automatically determines, calculates, and displays experimental results, with power down storage functions.
4. The repeatability and repeatability of the measured results were improved by using a magnetic can closed sensor with equally spaced multipoint calibrations.
