Product Description

ASTM D971 Standard Test Method for Interfacial Tension of Oil against Water

Product Description

ASTM D971 Standard Test Method for Interfacial Tension of Oil against Water is suitable for measuring the non-equilibrium conditions of mineral oil in water interfacial tension (Liquid-liquid interface).It can also be used to determine surface tension of various liquids (Liquid-gas interface).The Surface Tension Meter is designed and made as per GB/T6541 "Test Methods for Interfacial Tension of Petroleum Products between Oils and Water (Ring Methods)".

Main Technical Features

1.It used electromagnetic force -balance-type transducer, improving the accuracy of the measurement
2.Demarcated one point and you can adjust the instrument, and it's very convenient.
3.the instrument can show current weight values and tension Equivalence
4.the instrument can revise the test result automatically
5.used high-quality screen, the life of screen extended
6.the instrument can save 255 records
7.the instrument has a mini- printer; you can print the test result any time.  
8.the instrument has RS232 interface equipment; it can connect to computer, and it convenient for data processing.

Applications

1.Oil aging test, especially transformer oil (ASTM D971)
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.
