SFZL-A Touch Screen Digital Display Automatic Surface Tension Meter

SFZL-A Touch Screen Digital Display Automatic Surface Tension Meter

1.Description    

      Intermolecular forces form the interfacial tension or surface tension of the liquid, the size of the tension value can reflect the physicochemical properties of the liquid and its material composition, is the coatings, ink industry to examine the quality of the product is one of the important indicators. Our company provides fully automatic tension tester based on the principle of circular method (platinum ring method), used to measure the surface tension of various liquids (liquid-gas phase interface) and the interfacial tension of liquids (liquid-liquid phase interface). This method is widely used for its advantages of simple operation and high accuracy.

Main performance characteristics:
* Adopting advanced electromagnetic force balance force sensor with high accuracy and high repeatability characteristics.
* 5-inch wide touch screen control, the current ambient temperature, the current tension, peak tension, equivalent tension and other information integrated display, operation is very simple.
* At the same time the design of platinum plate, platinum ring two test methods, you can choose one of them, you can also choose two at the same time.
* Operation is fully automated, eliminating all human errors. The platinum plate automatically locks the liquid interface, the platinum ring displays the tension curve, automatically locks the peak tension without any conversion, and directly displays the tension value on the screen.
* Full range of automatic calibration, support weight weight correction, pure water tension correction, ethanol tension correction.
* Compact ball screw lifting system, no noise, rising and falling speed adjustable.
* Convenient platinum plate, platinum ring lifting bracket, the user is very easy to uninstall, at any time you can use standard weights to calibrate the accuracy of force value.
* One-key tare function, the number does not jump, zero position without drift.
* Ambient temperature automatic compensation, water, ethanol as a standard, automatic conversion of the tension value of the specimen at 20 ° C.
* Optional data acquisition software
