SH107 Auto Interfacial Tester Platinum Ring 0.1mN/m Precision Temp Calibration for Oil Liquid Testing

SH107 Auto Interfacial Tester Platinum Ring 0.1mN/m Precision Temp Calibration for Oil Liquid Testing

  Model SH107 fully automatic interfacial tensiometer is fabricated in compliance with GB/T6541 standards. It applies the platinum ring testing method to gauge surface tension of all kinds of liquids at liquid-gas boundaries, as well as the oil-water interfacial tension between mineral oil and pure water under non-equilibrium testing environments. Built around a single-chip control unit, the device runs with high automation levels and steady, trouble-free performance, and the operation workflow is straightforward. Once you pour the sample liquid into the measuring cup, just tap the start key, and the equipment will run the full measurement cycle independently, then work out the tension reading with the custom parameters you entered earlier.

  To explain interfacial tension clearly: Oil-water interfacial tension stands for the surface force formed where petroleum products meet pure water that cannot mix together, with the unit mN/m. For power system insulating oils, the interfacial tension people usually mention specifically refers to the tension between oil and water layers, shorted as oil product interfacial tension.

Equipped with a single-chip control core and a large LCD display screen, the machine features a neat, compact look. It delivers outstanding measuring precision and consistent repeatability during repeated tests. All custom parameter settings remain stored even after unexpected power cuts, and a built-in temperature compensation function is available. It is widely adopted to test interfacial tension indicators for finished goods and production lines across power generation, petrochemical, chemical manufacturing and railway sectors.
