I.Main Function and Working Principles

HZ1721 interfacial tension meter is an easy-operated machine that can quickly and accurately calculate the interfacial and surface intension of various kinds of liquid. It’s used to calculate the interfacial and surface intension of industrial oil in hydraulic department and electric department to strengthen the supervision of insulating oil. Besides, it’s also widely used in petroleum industry, chemical industry, research departments and education departments.

This machine mainly consists of torsion wires, platinum rings, sample brackets, dial scales, cursor pointer, kickstand, lever brackets, sharp tuning worm gears, testing worm gears and sample kickstands. The machine imposes torsion to torsion wires through revolving the testing worm gear, and balancing the torsion with the liquid surface’s tension caused by the platinum ring. When the torsion keeps increasing until the liquid surface breaks, the number shown on the dial scale is the value of tension. (expressed in M, Unit: mN/m) Then the real value of interface tension, δ, is calculated through M multiplied by correction factor F.

This product is manufactured according to JB/T9388-2002 Technical Requirements for Interfacial Tension Meter, ISO1409-1995 Surface Intension Measurements for Plastic, Rubber, Polymer Dispersion and Latex and SH/T 1156-95 Surface Intension Measurement for Synthetic Latex.
