The JCY series contact angle meter is a new standard instrument used to measure the contact angle of solids and the surface tension of liquids. Using advanced optical video measurement technology, images captured by high-precision industrial cameras are sent to a computer for data processing. Fully functional and very easy to operate. Compliant with international standards such as ASTM D 724, ASTM D 5946, ISO15969, etc. The scientific research in colleges and universities, which is widely similar to the quality testing box in industrial and mining enterprise laboratories, is a teaching experiment.

The main technical features of JCY series contact angle tester are:
1. Adopting advanced dedicated CCD digital industrial cameras with high resolution, high precision, and high clarity. Image count: 1280 × 1024, frame rate: 15 or 45/second;

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

3. The injection system is adjustable in multiple directions (up and down, left and right, tilt), making it easy to obtain the desired droplets;

4. Using a micro injection device, the droplet size can be accurately controlled, and manual control can reach 0.1 μ l (using a high-precision injection pump can reach 0.05 μ l);

5. Three dimensional sample stage;

6. CONTA3.0 contact angle direction software, based on operating platforms such as WINDOWS XP and WINDOWS 7, has a user-friendly interface, easy operation, powerful functions, and accurate measurement. Specifically, it includes:
① The θ/2 method and tangent method can be used to calculate the contact angle of a solid, which can be automatically calculated or manually (corrected) calculated;

② Comes with standard angles of 15 °, 45 ° C, 90 °, and 135 °, which can be automatically calibrated;
③ Calculation of surface free energy, droplet volume, and solid adhesion force using one liquid method and two liquid method;

④ The dynamic contact angle analysis system can continuously take photos, automatically record the changes in contact angle at different times or different tilt angles, and analyze the forward angle, backward angle, and rolling angle;

⑤ 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;

⑥ The horizontal adjustment method combining software and hardware can accurately and conveniently find the horizontal baseline;

⑦ 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;

⑧ Test environment setup, liquid dictionary maintenance;

⑨ Software brightness correction function
