LR-SDC-1000 Penguji Sudut Kontak Optik Platform Besar
Ringkasan
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, analisis kontur gambar cara untuk mengukur Sudut kontak permukaan, keterbasahan, ketegangan antarmuka meja, energi permukaan, seperti kinerja, peralatan hemat biaya, fungsi yang komprehensif, high test precision and can meet the large size products, such as TV flat glass and other special products with conventional sample measurement needs.
