ASTM D5946 Portable Contact Angle Meter Surface Energy Tester Goniometer

ASTM D5946 Portable Contact Angle Tester Surface Energy Tester Goniometer

1. Summary
The contact angle refers to the tangent line of the gas-liquid interface formed by the intersection of gas, liquid, and solid, that is, the Angle θ between the liquid surface and the solid-liquid boundary. The measurement of contact angle is currently the main method for surface performance testing.
The LR-SDP-300 handheld contact angle measuring instrument uses optical imaging principles to measure the contact angle, moisture content, surface energy and other properties of sample surfaces through image contour analysis methods. The handheld contact angle measuring instrument is a specialized instrument suitable for outdoor and large-scale sample surface performance testing. The instrument is small in size, easy to carry, cost-effective, with high measurement accuracy and accurate low angle testing.

Contact angle measuring instruments are widely used in various industries, such as mobile phone manufacturing, glass manufacturing, surface treatment, material research, chemical engineering, semiconductor manufacturing, coating ink, electronic circuits, textile fibers, medical biology, etc. Contact angle measurement has become an important instrument for evaluating surface properties.
