Overview
JYW-200 automatic table interfacial tension meter is an instrument used for the measurement of liquid surface tension. It uses physical methods to test the surface of liquids and the interfacial tension value between liquids and liquids. The instrument can quickly and accurately measure the surface and interfacial tension values of various liquids. It is used to test the interfacial tension value of electrical oils in the hydropower sector to strengthen the supervision of insulation oil quality. It is used to test the surface tension value of liquids in the petroleum, chemical, scientific research and other departments to strengthen liquid analysis. It is used in scientific research and teaching in colleges and universities and research institutes.
Features

Steps
1. The software automatically adjusts to zero.
2. Automatic peak hold.
3. Automatically calculate the test results.
4. The automatic correction factor is calculated and the actual tension value is displayed.
5. Automatically calculate the average value of the actual tension value of multiple experiments.
Notice
• The instrument is suitable for testing various strong acid and alkali solutions, but the equipped quartz glass is required.
• Make sure that the software automatic zeroing function is normal before testing.
• Repeatability error is not more than +/- 0.2%, pay attention to environment interference when using.
• Precision requirements ≤ 0.2mN/m, it is recommended to use secondary distillation water or ethanol for calibrating.
