Main features:
1 , the use of computer multimedia technology, optics and CCD camera combine to make images of droplets clearly displayed on the computer screen , you can store the image at the moment for the measurement , to avoid measurement failure caused due to evaporation of liquid .
2 , a special kind of manual tilting platform and processing system easy to measure advancing angle and receding angle .
3, with the curve baseline correction , automatic image analysis .
4 , dynamic and static contact angle , dynamic contact angle changes , forward angle / back angle , tilt angle , roll angle analysis .
5, the solid surface can estimate : Fowkes a liquid method , Owen two liquid method , Zisman method , Acid-Base Act and other surface tension surface free energy estimates.

6 , surface correction : convex surfaces, concave surfaces, surface roughness correction .
7 , a variety of test methods: hanging drop method, a droplet method.
8 , the contact angle values about the calculation of compensation .
9 , database management functions: query , backup , compression, export EXCEL form.
