Principle
The instrument uses the Opencv graphic profile analysis software to automatically test the left corner, right corner and average angle of the droplet in real time by the static droplet method, and provides real-time test Linear dispersion and data list. The dynamic test includes the real-time automatic analysis of the forward angle, backward angle and tilt angle by the turning method, and the measurement of the forward contact angle and the backward contact angle by the volume increase and subtraction method. The interfacial tension value range of the liquid surface can also be measured by the hanging drop method and CMC, and the interfacial tension value range of the liquid surface can be tested from 0.001mN/m to 1000mN/m.
