 =====What is Conductivity?=====
 Conductivity, or specifically Electrolytic Conductivity (EC), is defined as the ability of a substance to conduct electric current. It is the reciprocal of the more commonly encountered term, resistivity. All substances possess conductivity to some degree, but the amount varies widely, ranging from extremely low (insulators such as benzene, glass) to very high (silver, copper, and metals in general). Most industrial interest is in the conductivity measurement of liquids, which generally consists of ionic compounds dissolved in water. These solutions have conductivities approximately midway between insulators and metallic conductors. This conductivity can be measured quite easily by electronic means, and this offers a simple test which can tell much about the quality of the water, or the make-up of the solution. A broad line of conductivity equipment is available to measure liquids ranging from ultra pure water (low conductivity) to concentrated chemical streams (high).
