JCY series contact angle meter manufacturer (droplet angle meter) is a standard type instrument used to measure solid contact angle (droplet angle), surface energy, and liquid surface tension. Adopting advanced optical video measurement technology, the images captured by high-precision industrial cameras are sent to a computer for data processing, with complete functions and very convenient operation. Compliant with ASTM D 724, ASTM D 5946, ISO15969 and other standards. Widely used for quality testing in industrial and mining enterprise laboratories, as well as scientific research and experiments in colleges and universities.

Main technical features:

1. Adopting advanced specialized digital cameras with high resolution, precision, and clarity; Maximum resolution: 1280 × 1024, frame rate: 15 or 45/second;

2. High brightness LED background light source system, with uniform illumination and continuously adjustable brightness;

3. The direction of the injection system can be adjusted (up and down, left and right, tilt), which can easily obtain the required droplets. 4. Using a micro injection device, the size of the droplets can be accurately controlled, and manual control can reach 0.1 μ l (using a high-precision injection pump can reach 0.005 μ l);

4. Adopting a micro injection device, the injection volume can be accurately controlled, with manual control reaching 0.1 μ l and high-precision injection pump reaching 0.05 μ l.

5. Three dimensional sample stage;

6. CONTA 3.0 contact angle analysis software, based on operating platforms such as WINDOWS XP and WINDOWS 7, has a user-friendly interface, easy operation, powerful functions, and accurate measurement values

① The contact angle method is used to measure the surface tension of solids. The automatic calculation function includes: θ/2 method, tangent method to calculate contact angle, which can be automatically calculated or manually (corrected) calculated; Comparison of left and right contact angles; Multi point contact angle comparison;

② Calculation of surface free energy, droplet volume, and solid adhesion force using one liquid method and two liquid method;

③ The dynamic contact angle analysis system can continuously take photos, automatically record the changes in contact angle at different times, and analyze the forward angle, backward angle, tilt angle, and rolling angle;

④ The suspended droplet method is used to measure the surface tension of liquids, and the latest calculation functions include: S-H table method, shape factor method;

⑤ The horizontal calibration method combining software and hardware can accurately and conveniently find the horizontal baseline;

⑥ The test results are saved in the database in the form of a test report, which can be compressed and backed up, and can automatically generate Excel files;

⑦ Test environment setup, liquid dictionary maintenance

⑧ Software brightness correction function
