Description
EZO™ Conductivity Circuit - Atlas Scientific
From chemical production to hydroponics, conductivity is a fundamental measurement of water chemistry. The Atlas Scientific EZO-EC Circuit reads conductivity, salinity, and TDS (PPM). Embedding this module into your machine gives you access to the same accuracy and functionality found in costly bench-top conductivity meters. If you need accurate readings that you can rely on, the EZO-EC circuit is the drop-in solution you have been looking for.
An E.C. (electrical conductivity) probe measures the electrical conductivity of a solution. It is commonly used in hydroponics, aquaculture and freshwater systems to monitor the number of nutrients, salts or impurities in the water.
Inside the conductivity probe, two electrodes are positioned opposite from each other, an AC voltage is applied to the electrodes causing cations to move to the negatively charged electrode, while the anions move to the positive electrode. The more free electrolyte the liquid contains, the higher the electrical conductivity.
