Features:

1. It adopts advanced electromagnetic force balance force sensor with high precision and high repeatability.

2, 5 inch wide touch screen control, the current ambient temperature, current tension, peak tension, equivalent tension and other information integrated display, operation is very simple.

3. At the same time, design two test methods: platinum plate and platinum ring. You can choose one of them, or you can choose two at the same time.

4, the operation is fully automated, eliminating all human error. The platinum plate automatically locks the liquid interface, and the platinum ring displays the tension curve, automatically locking the peak tension, without any conversion, the direct screen displays the tension value.

5, full range automatic correction, support weight weight correction, pure water tension correction, ethanol tension correction.

6, compact ball screw lifting system, no noise, adjustable rise and fall speed.

7. Convenient platinum plate and platinum ring lifting bracket, the user is very easy to uninstall, and the standard weight can be used to calibrate the accuracy of the force value at any time.

8, one-button peeling function, the number does not beat, zero drift.

9. The ambient temperature is automatically compensated. The water and ethanol are used as standard standards, and the tension value of the sample at 20 °C is automatically converted.

10. Optional data acquisition software.

11. Meet the following standards but not limited to the following standards:

   GB/T6541-86 Petroleum product oil-to-water interfacial tension method

   ISO 1409-1995 Determination of surface tension of plastics, rubber, polymer dispersions and latex
