DSA-X ROLL Expert-Grade Whole-System Tilting Contact Angle Measuring Instrument
Beituo Science independently designs and manufactures the DSA-X ROLL expert whole-instrument-tilt optical contact-angle measuring instrument. An advanced high-resolution industrial camera and LED cold light source capture clear images, which newly optimized software fits and analyzes to produce accurate test data. A high-precision, high-torque stepper motor maintains stability during high-accuracy tilt-angle measurements. The entire process, from dispensing to rotation, is automated, with automatic capture at the instant of rolling and an automatic locking function.

For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
