10. The instrument has a reasonable structure and works independently without additional equipment
Principle
The instrument adopts two test principles: platinum plate method and platinum ring method. When using platinum plate test, the displayed value is the surface tension value; when using platinum ring test, the displayed value automatically locks the maximum force value of the sample, and automatically calculates the surface/interfacial tension value through calculation software. The instrument detects the tension change of the liquid surface or interface through a precision Sensor, and cooperates with an automatic lifting platform and a data processing system to complete accurate measurement.
Applications
Surfactant measurement, emulsion surface tension test, petroleum product interfacial tension test, polymer dispersion test, rubber surface tension measurement, oil-water interfacial tension detection
Standards
GB/T 22237-2008、JB/T 9388-2002、JB/T 18396-2001、SH/T 1156-95、GB/T 6541-86、ISO 1409-1995、ISO 6295-1983、GB/T 5549、ISO14090-82、ASTM D1417、EN14370、ZB2025-93、GB2960-82
Steps
1. Select the test method (platinum plate method or platinum ring method)
2. One-click reset of full scale
3. Automatic calibration of full scale
Step 4 Place the specimen
5. Start automatic measurement
6. Read the display data or process the data through software
Notice
• Pay attention to the application of peak automatic hold function when using platinum ring test
• Measurement of surface tension with surfactants or volatile matter may change over time
• Platinum plate method is suitable for surface tension testing of medium and high viscosity liquid samples
• Both test methods allow measurement of interfacial tension between dissimilar liquids
• Accuracy calibrating requires 2 distillations of water and pure ethanol as a standard
• The automatic temperature compensation function requires the use of 2 distillations of water and pure ethanol as the standard
• Different temperature control devices can be selected according to test requirements
