Portable Contact Angle Tester Meter LR-SDP-300
1· Summary
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-SDP-300 handheld contact Angle measuring instrument is the use of optical imaging principle, through image contour analysis method to measure the sample surface contact Angle, wettability, surface energy and other properties, handheld contact Angle measuring instrument is a suitable for outdoor and large size sample surface performance test special equipment, The equipment is small in size, easy to carry, cost-effective, high measurement accuracy, low Angle accurate test.

Application
Contact Angle measuring instrument is widely used in various industries, in mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemistry and chemical industry, semiconductor manufacturing, coating ink, electronic circuit, textile fiber, medical biology and other fields, contact Angle measurement has become an important instrument to evaluate the surface performance.
(Some test functions need special accessories to be purchased)
1. The wetting behavior of liquid on solid surface such as spreading, penetration and absorption, and the static contact Angle is measured by the block drop method;
2. Forward Angle, backward Angle, contact Angle lag, rolling Angle and dynamic contact Angle measurement of material on solid surface;
3. Continuous real-time research and process recording of absorbing materials, and curve analysis of contact Angle change with time;
4. Measurement of contact Angle of various special materials, such as powder, curved surface, superhydrophobic/superhydrophilic samples;
5. Suspension drop method to measure the interfacial tension and its polarity and dispersion components of various liquid surfaces;
6. Calculate the Surface free energy of solid and analyze its polar dispersion component;
7. Analyze the adhesion energy of liquid on solid surface and evaluate the uniformity and cleanliness of solid surface.
