IFT Oil Interfacial Tension Surface Tension Testing Equipment

IFT Oil Interfacial Tension Surface Tension Testing Equipment

Oil surface tension tester is a device based on the principle of interfacial tension or surface tension formed by the intermolecular forces of liquid molecules, which reflects the physical and chemical properties and substance composition of the liquid by measuring the tension value.

Key Functions and Features

Surface tension is a fundamental property of liquids, arising from intermolecular forces. Its magnitude directly reflects the physical and chemical properties of a liquid sample and is a critical indicator of product quality.

This instrument offers the following functions and features:

High-Precision Measurement: Utilizes an electromagnetic force-balance transducer for enhanced measurement accuracy.

Simple Calibration: Features single-point calibration for quick and convenient instrument adjustment.

Real-Time Display: Shows both the current weight value and its equivalent surface tension value simultaneously.

Temperature Compensation: Integrated temperature detection circuit provides automatic temperature compensation for test results.

Clear Interface: Features a 240×128 dot matrix LCD screen with plain buttons and a screen protection function.

Data Logging: Stores up to 255 historical records with time stamps.

Integrated Printing: Built-in high-speed thermal micro printer delivers fast, high-quality printing, including offline capability.

Computer Connectivity: Equipped with an RS232 interface for connection to a computer, facilitating data processing.

Technical characteristics

Optimized Precautions:

Working Environment:

Ensure the instrument operates within the environmental specifications outlined in Chapter 4.

Platinum Ring:

Alignment: The ring plane must be parallel to the horizontal surface.

Condition: Maintain ring roundness and cleanliness.

Cleaning Procedure:

Wash with detergent.

Rinse thoroughly with pure water.

Heat the platinum wire in an alcohol lamp's oxidation flame until orange-red.

Test Cup:

Condition: Must be clean before use.

Cleaning Procedure:

Wash and scrub.

Rinse with hot water.

Perform a final rinse with pure water.

Drain completely.

Pure Water Source:

Use multi-distilled water for optimal results.

Note: Some commercially available purified drinking water may meet experimental requirements based on testing.

Instrument Calibration:

Calibrate the instrument weights (via the settings menu) if:

The instrument experiences significant physical shock.

The instrument is relocated.
