A visual high temperature contact angle tester is an instrument used to measure the contact angle of a liquid on a solid surface. Here's a quick rundown of how to use the Visual High Temperature Contact Angle Tester:
Preparation: Place the tester on a level, stable table and make sure there are no strong magnetic fields or other sources of interference around the instrument. Connect the power cord and turn on the instrument power switch.
Adjust the test platform: Place the sample to be tested on the test platform and adjust the levelness of the platform using the adjustment screws to ensure that the sample surface is perpendicular to the lens of the tester.
Adjust the light source: Select the appropriate light source brightness and angle as needed. The angle of the light source can be adjusted by rotating the light adjustment knob to get the best test results.
To start the test: Use a microsyringe or pipette to drop a drop of liquid onto the surface of the sample. The shape of the liquid on the solid surface is then observed through the tester's display and the contact angle is recorded.
Data processing: Once the test is complete, the data can be exported to a computer or other device for further analysis and processing.
Cleaning and maintenance: After the test is completed, clean the test platform and lens in time to keep the instrument in good working condition. Instruments are calibrated and maintained regularly to ensure the accuracy and reliability of test results.
It should be noted that when using the visual high-temperature contact angle tester, it should be operated in strict accordance with the operating procedures of the instrument and pay attention to safety matters. At the same time, appropriate test methods and parameters should be selected according to actual needs to obtain accurate and reliable test results.
