Portable optical contact angle meterUsing video appearance contour analysis method, measuring the contact angle between liquid and solid, measuring the surface energy of solid, applied in industries such as glass manufacturing, touch screen detection, circuit boards, etc. The portable optical contact angle meter is used to test the wettability of liquids on solids, that is, to determine the wettability of various liquids by measuring the size of the contact angle formed by various liquids on various solid materials. The method is to drop a liquid droplet on a solid horizontal plane and test the solid liquid gas three-phase boundary point on the surface of the solid. The angle formed by the two tangent lines of the gas-liquid interface and the solid-liquid interface sandwiching the liquid phase is called the contact angle.
The main features of portable optical contact angle meter are:
1. Exquisite design, flexible and portable
2. Measurement with high repeatability
3. The software interface is user-friendly and easy to use
4. Comes with battery, can work for 8 hours
5. Data can be transmitted wirelessly
Portable optical contact angle meter method and accuracy:
(1) Note:; Provide four static contact analysis methods, which can be selected according to different experimental images and usage habits, flexible and convenient.
(2) Introduction to droplet method, solid surface energy estimation, and θ/2 method; By moving the curve ruler, the left turn calculates the left water contact angle measurement instrument, while the right turn calculates the right water contact angle measurement instrument.
The measurement method of portable optical contact angle meter: seat drop method; Forward angle method; Backward angle method; Inclined plate method; Suspension drip method; Oscillation drop method; Single fiber measurement methods, etc.
Portable optical contact angle meterIt is a well-designed and compact contact angle tester that can be used to test wetting, adsorption, uniformity, surface free energy, spreading, absorption, cleanliness, printing suitability, etc. It can be widely used in industries such as packaging, coatings, printing, and materials engineering for rapid online testing and quality control in production processes.
