**Contact Angle Meter / Contact Angle Measuring Instrument / Testing Equipment (YL-100)**
**1. Application**
This contact angle meter is primarily used to measure the wettability of liquids on solid surfaces. By analyzing the contact angle, it helps calculate and evaluate the surface energy, adhesion properties, and interfacial tension between a liquid and a solid. This device is widely applied in industries such as petrochemicals, pharmaceuticals, papermaking, and materials science, supporting both research and educational purposes.
**2. Product Features**
- Compact and user-friendly design with one-touch operation.
- High-resolution video capture for image analysis and report generation in Word or Excel format.
- Cold light source with adjustable brightness for accurate imaging.
- International standard stainless steel capillary tube for precise droplet formation.
- Multiple testing methods including 20° wide height method and ellipse method for improved accuracy.
- Supports various tests like contact angle, rolling angle, and dynamic measurement.
- Software allows image scaling and direct saving of test results.
- Advanced software functions include suspended drop method, interfacial tension measurement, circle/ellipse fitting, curved surface testing, and more.
- Offers multiple surface energy calculation methods such as Fowkes, OWRK, Zisman, and EOS.
**3. Standards**
- GB/T 24368-2009: Determination of hydrophobic pollutants on glass surfaces
- SY/T 5153-2007: Method for measuring reservoir rock wettability
- ASTM D724-99 (2003): Test method for surface wettability of paper
- ASTM D5946-2004: Measurement of contact angle between plastic film and water
- ISO 15989: Water contact angle measurement of plastic films and corona-treated thin plates
