QD600 Overall Tilt Contact Angle Meter

Suitable for studying the wettability, retention, and adhesion of liquids on solid surfaces, with an overall tilt angle of up to 180°.It can test dynamic contact angle(including roll off angle,Advancing angle, receding angle, hysteresis angle)

Product Details​

Fully automatic integrated tilt measurement of rolling angle eliminates the hassle of adjusting baseline inclination. Achieves a full tilt range of 180°, featuring comprehensive dynamic analysis for water drop angle detection (including measurement of liquid contraction/expansion dynamics, wetting dynamics, and rolling/sliding dynamics).Comprehensively evaluate the actual application performance of surfaces.
