| The instrument uses MCU control, was under unbalanced conditions, the measurement of liquid interfacial tension. Simple, reliable, automatic calculation of tension, allows determination of petroleum, chemical, power, pharmaceutical and other liquid products for the interfacial tension. Using new and improved magnetic tank enclosed electromagnetic force balance sensors, improve the response speed and linearity; new sensor calibration point can only solve the previous generation sensors require multi-point calibration to ensure the accuracy of the linear problem, replacing the zero potentiometer and span potentiometer adjustment, to make it more stable and reliable; the instrument also uses a sine wave oscillator Wien Bridge-precision high-speed operational amplifier, with little distortion, easy debugging features. |
