Measuring Range 0-180° Automatic Water Drop Angle Tester for Petroleum

Product Overview

The automatic water drop angle tester measures the angle formed when a liquid droplet contacts a solid horizontal plane at the solid-liquid-gas three-phase junction point. Using optical imaging principles and image profile analysis, this equipment measures surface contact angle, wetting performance, surface interfacial tension, forward and backward angles, surface energy and other material properties.

The instrument features a fully automatic liquid inlet device, comprehensive functionality, and high expandability, making it suitable for various routine measurement requirements. It has been widely adopted by universities and industrial enterprises.

This hydrophilic angle contact angle measuring instrument evaluates liquid wettability on solids by measuring contact angles and calculating liquid free energy, adhesion tension, and other critical indicators. Our factory independently develops these instruments, offering different types to meet diverse user requirements.

Measurement Methods & Accuracy

The instrument provides four static contact analysis methods that can be selected based on different test pictures and usage habits for flexible and convenient operation.

Liquid Drop Method: Includes solid energy estimation and θ/2 method introduction. By moving the curve ruler, left rotation calculates the left automatic water drop angle, and right rotation calculates the right automatic water drop angle.

Measurement Procedure: After freezing the picture, sequentially click the left and right ends of the droplet and the top of the droplet with the left mouse button. Results are automatically calculated and displayed. For quick analysis, measurements can be taken without freezing the image. If clicking errors occur, use the right mouse button to cancel selection and recalculate.
