LR-SDC-1000 Large platform optical contact Angle Tester
Резиме
Contact Angle refers to the tangent line of gas-liquid interface made at the intersection point of gas, liquid and solid phases, which is the Angle θ between the liquid side and solid-liquid boundary. The measurement of Contact Angle is the main method of surface performance detection at present.
LR-SDC-1000 type platform contact Angle measurement instrument is using the principle of optical imaging, анализа контуре слике начин за мерење контактног угла површине, влажење, међуфазна напетост стола, површинска енергија, као што су перформансе, опрема исплатива, свеобухватне функције, high test precision and can meet the large size products, such as TV flat glass and other special products with conventional sample measurement needs.
