Introduction: SDP-300 portable contact angle measuring instrument is mainly used for measuring large-size samples, or measuring contact angles of special samples, or occasions where measurement sites need to be frequently replaced. For example, computer contact screens, television screens, large-size glass, car covers, etc., conventional contact angle measuring instruments cannot meet the requirements. The portable contact angle measuring instrument has been applied to the measurement research or quality inspection of materials, automobiles, circuit boards, touch screens, televisions and the like due to its lightweight advantages. It can be perfectly matched to the full-time automatic detection of assembly line production. Features: 1. Light source system: LED light cold light source, the service life is better than 20,000 hours, and the emission of heat is ultra-low, which significantly reduces the effect of heat on the liquid volume volatilization. Leading light guide design and materials are used to ensure that the light is evenly parallel and sharp and sharp. 2. Optical system: high-fidelity telecentric lens, to avoid the imaging distortion generated by the ordinary lens, to ensure that the contact angle measurement data of each angle range is close to the actual data. 3. Camera System: Industrial-grade camera, high-speed acquisition of 30 images per second, USB2.0/3.0 data transmission, providing excellent imaging quality. 4. Injection system: Optimized design of the injection system with an accuracy of ±0.1μl, allowing quick replacement of liquid samples for surface energy testing. Single-tube liquid can be measured continuously more than 200 times. Single test time within 2s. 5. Analysis software: analysis algorithm, differential circle method and differential ellipse method, accurately measure the left and right contact angles and forward and receding angles. Meet a variety of routine and special occasions for sample measurement. 6. Easy to operate: quick measurement, quick access to data, and export a comprehensive data report. There is no need to perform calibration every time, no need for human analysis and adjustment. With one hand, all measurement operations can be performed, which is suitable for quick and convenient industrial quality inspection. 7. Lightweight: Size: 95×100×60mm (length×width×height).
