GD-6541A Liquid Gas Surface Tension Testing Equipment

Description

Brief Introduction:

• The instrument is designed and made as per the National Standard of People’s Republic of China GB/T******6 (***1) “Test Method for Interfacial Tension of Oil against Water by the Ring Method”. 
• It is suitable to determine the interfacial tension between mineral oils and water under non-equilibrium condition (Liquid-Liquid interface). 
• It can also be used to determine interfacial tension of various liquids (Liquid-Gas interface). 
• The instrument adopts large LCD screen and blank button, so it is automatic, reliable, and simple and with good repeatability. 
• Turn on the instrument and operate the instrument as per the prompt of menu, and you can complete the test as per the prompt. 
• The instrument has function of automatic temperature compensation, clock control, printing, and automatic average value calculation. It can connect to a computer through RS**2 interface. 
• You can also send the test data to a handheld computer for analysis. It is the best choice to make determination for interfacial tension test.
