It is an economical meter for online measurement of specific Conductivity of solution using a Conductivity cell for RO plant or DM plant applications. It enables to measure the Conductivity without manual balancing and specific Conductivity is read directly on a digital panel. This is available in panel mounting facility in compact size. PRINCIPLE Conductivity is the ability of a solution, a metal or a gas - in brief all materials to pass an electric current. In solutions the current is carried by cations and anions whereas in metals it is carried by electrons. How well a solution conducts electricity depends on a number of factors: • Concentration of ions • Mobility of ions • Valence of ions • Temperature All substances possess some degree of conductivity. In aqueous solutions the level of ionic strength varies from the low conductivity of ultrapure water to the high conductivity of concentrated chemical samples. Conductivity may be measured by applying an alternating electrical current (I) to two electrodes immersed in a solution and measuring the resulting voltage (U). During this process, the cations migrate to the negative electrode, the anions to the positive electrode and the solution acts as an electrical conductor.
