Typical fields of application  of surface tension meter measuring surface tension                                                                   
- Teaching experiment for demonstrating the method for measurement of surface tension
- Quality control: ink, paint, plating fluid, cosmetics and transformer oils, etc.
- Detergent ~ surfactant’s absorbing speed, property, discussion of proper concentration

Performance Features  of surface tension meter measuring surface tension                                         

² First type of the world that measures surface tension using Wilhelmy plate manually.

² Long and best seller model with reasonable price and specifications

² Analytical balance with fast data update speed and positioning stage with accuracy of 0.01mm  eliminates personal error

² Analytical balance provides higher precise than weighing unit using torsion wire

² Surface tension meter measuring surface tension Measuring result is real time LED digital readout

² Simple operations with manual and simple calibration with standard weights (50g)

² 3th generation Wilhelmy Plate method presents you the performances below.:

  Variations of surface tension over time in the presence of surfactant.

  Surface tension of medium-to high viscosity liquids (up to about 104105 CP.s)

² Possessing both Wilhelmy plate method and Du Noüy ring methods (Latter method needs manual calculating by Excel file provided from us)

² Standalone. Need not connect to PC.
