Surface tensiometer model A3 is manual standard version standalone instrument that equipped with analytical balance and high precise positioning stage. It can be used to measure surface tension of liquids based on Wilhelmy plate and Du Noüy ring methods rapidly and simply.
Typical fields of application of surface tensiometer
- 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 tensiometer
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 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 104~105 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.
