This automatic Du Noüy Ring Tensiometer measures the Surface Tension of Single-Phase Samples and the Liquid-Liquid Interfacial Tension of Multi . The surface tension meter of the platinum plate method is divided into two categories, one is the classic algorithm based on zero buoyancy method and another one is based on the Young-Laplace equation correction method. The classical platinum plate method and the platinum ring method are both modified with zero contact angles as the . The unit for surface tension is one newton per meter (N/m). A Newton is equal to 1 kg-m/s 2. To work out the units on your own, simply solve the equation with just units. S = kg/m 3 * m * m/s 2 * m. Two of the meter units cancel out two of the per meter units and you are left with 1 kg-m/s 2 /m or 1 N/m.
