Conductivity meters measure the ion capacity in aqueous solution to carry electrical current. Capacity range 1.030.6l/h, 102bar. The generated current is proportional to the total conductivity of the solution and is effective in removing the polarization effect. Besides conductivity, the strength of the magnetic field depends on the permeability, In the following, the damping effects of eddy currents are established using Maxwells equations. Designing small cells closer together can be necessary to measure extremely low conductivity, while the opposite is true for higher conductivity. Certain devices can function in temperatures up to 270C. For extremely low conductivity, such as in ultrapure water, each degree Celsius change induce a 5% change in conductivity, whereas extremely concentrated ionic solutions require temperature compensation of only 1.5% per degree Celsius.
