The electrical conductivity measurement is a fast and reliable method for estimating the concentration of ions in the solution. Hygrometry in the sciences and industry has many applications that measure the concentration of ions in aqueous solutions the most important application.
It is usually used to measure the electrical conductivity of a solution of an alternating current (I) by two plates of the electrode to a portion of the solution enclosed between the two plates with constant momentum. By measuring the potential difference (V), the resistance (R) is obtained and Knowing the constant Tl (Ø) [L separation divided by the effective surface of the electrodes (A) (K) is calculated according to the following equations and is shown by the conductivity meter:
R = V / I Ø = L / A R = Ø / K
The formation of layers of ions along with electrodes (polarization or polarization) leads to the formation of two-layer capacitors and an error in measuring resistivity that prevents interference with the use of alternating current and porous electrode surface (plating).
It should be noted, however, that this problem does not go away in high concentrations. The CTR 80 conductivity meter is a laboratory and industrial device designed to measure the electrical conductivity of the solutions and, unlike the usual guidance systems, operate with four-pole electrodes. In this type of electrodes, developed by Zag Chem Co., four conductive conductors Which do not need to be plasticized, and a special insulating compartment is used. This array completely eliminates the effects of polarization in a wide range of concentrations and promotes a fast balance between the solution and the electrode. These types of electrodes, despite the low cost, efficiency, excellent precision And they have the smallest amount of sample Just making.
Uses for industrial use: To measure purely water-to-sea water concentrations.
Laboratory items: All conductivity measurements and related measurements, in a wide range of concentrations.
