GD-6541AT Transformer Oil Automatic Interfacial Tension Tester

Reference

Automatic Surface tension meter conforms :

1.GB/T6541 Standard Test Method for Interfacial Tension of Oil against Water by the Ring Method.

2.ASTM D971 Standard Test Method for Interfacial Tension of Oil Against Water by the Ring Method

It is used to determine the interfacial tension between mineral oils and water under

non-equilibrium condition (Liquid-Liquid interface).

The autoamtic type surface tension meter can also be used to determine interfacial tension of various liquids (Liquid-Gas interface).

The surface tension meter 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 surface tension meter has function of automatic temperature compensation, clock control, printing, and automatic average value calculation.

It can connect to a computer through RS232 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.
