The fully automatic surface tension meter adopts a fast and reliable quality control mode. After setting the measurement parameters, it can accurately measure and display the tension value. It can independently set the measurement range, number of test data, and average measurement value, making it an ideal tool for research and development. It is equipped with corresponding software and connected through USB to 232 serial port cable, with high data temperature and repeatability.The interface tension tester is developed and manufactured by Beijing Hake. The contact angle is not complicated, which is the semi-circular shape naturally formed by liquid droplets on the surface of a solid relative to the outer tangent of the solid plane. The application of contact angle is very extensive, and it can even be said to involve every detail around us. For example, we hope that the car glass will not be stained with rain, but conversely, we hope that the paint on the car steel plate will peel off. Other areas such as pesticides and vegetable leaves, coatings and interior and exterior walls, insulating oils and materials, surface modification of nanomaterials, and so on, are countless from teaching and research, industrial and agricultural production to daily life.
