VTSYIQI Automatic Interfacial Tension Meter Surface Tension Meter with ASTM D-971 Standard Platinum Ring Method 110V or 220V Range 0 to 1000 mN/m Accuracy 0.1mN/m

VTSYIQI Automatic Interfacial Tension Meter Surface Tension Meter with ASTM D-971 Standard Platinum Ring Method 110V or 220V Range 0 to 1000 mN/m Accuracy 0.1mN/m Introduction： Using a 4.3-inch touch screen, all operations and information are completed or displayed on the screen. It can be used to measure the surface interfacial tension of liquids Simple and fast operation. Automatic measurement with high repeatability can be achieved for the set measurement conditions. Application field: 1) Oil aging test, especially transformer oil (ASTM D-971) 2) Determination of Surfactant Effectiveness in Wetting Agents and Cleaners Test Surfactant Solution Concentration. 3) Canning approval and cleaning validation in the food industry. 4) Interfacial tension measurements for quality control and optimization of emulsifiers. 5) Cooling lubricant surface tension test. Measurement methods: Use the Du Nouy ring method method to measure the surface tension and interfacial tension. Manual testi
