Measurement Method
Theoretically, water free of any contaminants will not conduct electricity. The ability to carry on electric current depends on the presence of ions; conductivity increases with increasing ion concentration. Conductance of a solution is calculated by measuring the electrical current between two chemically inert platinum(Pt) coating electrodes set a fixed voltage source and immersed in water sample. Conductivity is customarily reported in micromhos per centimentre. In the International System of Units, the reciprocal of the ohm is the siemens (S) and conductivity is reported as millisiemens per meter (mS/m); 1 mS/m=10 μmho/cm and I μ s/cm=1 μmho/cm. The constant(K) of electrode: K=10.0 for conductivity>20 ms/cm; K=1.0 for conductivity 0.02~20 ms/cm
