Typical fields of application                                                                       

- 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：                                                                      

² The world's first portable classic surface tension meter based on the principle of DuNouy Ring or Wilhelmy Plate method

² The cost performance ratio of the products is very high, the price has great advantages, and the test performance is stable

² The micro sensor with higher speed and accuracy (1mg) and optical positioning stage with accuracy 0.01mm can effectively reduce the influence of measurement value caused by human error

² Precision micro sensor technology has higher precision, better repeatability, and more reliable measurement value than other manufacturers' torsion wire sensor

² The measurement results are directly displayed on the LED screen in unit “mN/m”, which is intuitive and clear

² he operation of the measured value is simple, and the balance can be quickly calibrated by simple external calibration of standard weights

² The principle of the third generation Wilhelmy plate method can automatically correct the buoyancy value and contact angle value, thus providing a strong guarantee for the realization of the following measurement values:

・  observe the surface tension value of surfactant which changes with time.

・  test the surface tension of medium and high viscosity samples (up to10⁴～10⁵ CP.s)

² Two testing principles, Wilhelmy plate method and DuNouy ring method, are provided. (Note: when platinum ring method is used to test surface tension, an excel file provided by our company shall be used to calculate and correct the corresponding value.)

² Independent operation, no need to connect computer
