MIL-II surface tension tester

This instrument is mainly used to test the surface tension of thin films, namely the surface wetting tension.
1. Test range: 1-100 millinewtons per meter; Resolution: 0.1 millinewtons/meter, error: 0.5 millinewtons/meter,
Measurement speed: 50 data/second;
2. Repetitive error: less than 0.3%;
3. The determination is mainly based on GB/T14216; Test method for wetting tension of plastic films and sheets
The determination of surface energy of plastic film is carried out. Using a mixture with lower surface tension,
Until the liquid film can last for 2 seconds. Wet the surface of the sample with a mixture of liquid for nearly 2 seconds,
Measure at least 3 times with this mixture, and the wetting tension of the mixture is the wetting tension of the sample.
4. The contact angle can be fully automatically tested by connecting a CCD camera to a computer CCD has more than 3 million pixels,
Image acquisition should not be less than 30 beats per second
5. Test software for Chinese operation, capable of automatic storage Report printing and output
6. Connect the computer to test the surface contact angle and analyze the wettability based on the size of the surface contact angle
7. The instrument provides manual and automatic injection methods for users to choose from
8. Manual and automatic lifting options are available, with a lifting distance of 100mm
9. Temperature range: -10 to 130 ° C; Temperature measurement: -60 to 450 ° C; 2 Pt100s (optional one);
Temperature resolution: 0.01 ° C (user selectable) ）10. It can measure the tension coefficient of liquids at different concentrations
11. Sample cup diameter: 50mm, 70mm, 100mm;
12. Power supply: 85-264V AC, 40-60Hz; Power: 40W (running), 5W (preheating)
