Electrical Conductivity Meter Principle

Edge ec hi2003 is incredibly versatile and can be used in several different environments.

Electrical conductivity meter principle.

Two plates are placed in a sample a potential is applied across the plates normally a sine wave voltage. Electrical conductivity meter is an instrument or a handy device designed to calculate the rate of conductivity of the exterior test material. An electrical conductivity meter ec meter measures the electrical conductivity in a solution it has multiple applications in research and engineering with common usage in hydroponics aquaculture aquaponics and freshwater systems to monitor the amount of nutrients salts or impurities in the water. Most conductivity measurements are made in aqueous solutions and the ions responsible for the conductivity come from electrolytes dissolved in the water.

An electrical conductivity meter ec meter measures the electrical conductivity in a solution. The conductivity meter a typical conductivity meter applies an alternating current i at an opti mal frequency1 to two active electrodes and measures the potential v. Hanna s edge ec hi2003 can measure conductivity tds and salinity and is a convenient table meter design. The conductivity meter then uses the conductance and cell con stant to display the conductivity.

Both the current and the potential are used to calculate the conductance i v. Conductivity changes with storage time and temperature. The utilization of these meters is generally witnessed in water monitoring systems to measure the number of nutrients impurities or salt in freshwater and aquafers in hydroponics. To carry a current a solution must contain charged particles or ions.

It is commonly used in hydroponics aquaculture and freshwater systems to monitor the amount of nutrients salts or impurities in the water. Conductivity measurements are used routinely in many industrial and environmental applications as a fast inexpensive and reliable way of measuring the ionic content in a solution. Principle by which this instrument measures the electrical conductivity is very simple. Conductivity or specific conductance of an electrolyte solution is a measure of its ability to conduct electricity the si unit of conductivity is siemens per meter s m.

In general pure solutions such as distilled water have low conductivity while saline or nutrient rich solutions such as seawater or fertilizers have. Electrical conductivity meter instrument used to measure the conductivity of the require desired material is called the conductivity meter. A conductivity meter sometimes called electrical conductivity meter water conductivity meter or ec meter measures the ability of a solution or liquid to conduct an electrical current. For example the measurement of product.
