Overview
HYQ-Z-102 manual contact angle tester is used to measure the contact angle between solid, liquid and gas three phases, and calculate the adhesion of liquid to solid, solid surface tension and solid surface energy by measuring contact angle. The instrument is widely used in petroleum, chemical industry, papermaking, dyestuff and various New material research and manufacturing fields. It uses microcontrol technology to transfer the ingested image into the computer for storage, analysis and printing. It has the characteristics of fast speed, accurate data and convenient operation.
Features
1. Measurement range of contact angle 0~ 180 °, accuracy +/- 0.1 °
2. Support automatic fitting measurement, baseline fitting measurement, manual three-point measurement, regional measurement method and other test methods
3. The injection system moves 35mm up, down, left and right, the sample stage moves 100mm left and right, and the front and rear 40mm.
4. Equipped with 0.7-4 zoom fixed focus high definition Microscope, Microscope moves up and down 80mm (fine-tuning 3mm)
5. Adopt manual injection system, knob-type Micrometer control, direct injection of liquid to avoid bubbles and cleaning problems
6. The software automatically saves measurement data and pictures, supports historical data viewing, deletion and instant screenshots
7. The maximum size of the sample is 300mm × 150mm × 10mm, and the Dimension is about 500 × 200 × 550mm.
Principle
The contact angle is defined as the angle between the gas-liquid interface and the solid-liquid interface at the three-phase interface of solid, liquid and gas, and is the scale for showing the Humidity of the solid surface. Measured with most solid droplets, the low contact angle indicates high Humidity (hydrophilicity) and easy sticking to the surface. The contact angle of the liquid in contact with the flat solid surface is determined by the end point of the water droplet Linear dispersion in the liquid-solid-gas bonding point and the contact point of the solid surface.
Applications
Petroleum, chemical, paper, dyestuff, New material research and manufacturing
Steps
1. Connect the computer and monitor power supply, and connect the instrument host Illuminant box power supply
2. Open the computer and double-click the contact angle software icon on the screen
3. After the software is opened, select the test method for measurement as needed
4. After the measurement is completed, the data is automatically saved and can be viewed, analyzed or printed
Notice
• Make sure the power connection is correct before starting the test
• Pay attention to the use of toolbar function keys when operating the software
• Uncommon functions can be extracted in the processing bar submenu
• Be careful to avoid bubbles when injecting liquids
• Keep the working environment of the instrument clean
