The Eddy Current Conductivity Meter measures the conductivity of a solution. It measures the flow of ions in a solution. It works by measuring the change in the amount of electric current flowing through the liquid when a voltage is applied to the electrodes. The meter works by having a conductive liquid and a reference electrode.
Electrical conductivity meter
The reference electrode is placed in contact with a pure water source. Then, when a specific solution is tested, the electrodes are connected to the liquid, and the liquid is between the two electrodes. This creates an electric field, which attracts ions from the liquid to the electrode. The liquid’s conductivity is the amount of current flowing through it.
This article will tell you everything you need to know about the Eddy Current Conductivity Metre.
What is an Eddy Current Conductivity Metre?
The eddy current conductivity meter measures the conductivity of a solution by measuring the alternating magnetic field generated by the solution. As a solution flows through the meter, it generates an alternating magnetic field measured by the meter.
The meter readings are directly proportional to the conductivity of the solution. This makes it an accurate method of determining the conductivity of a solution.
Emitting an alternating magnetic field is the simplest way of measuring the electric current concentration in a solution. The current induces a change in the sensor's magnetic field, which is measured and recorded.
Eddy current conductivity meters use electric current to determine the concentration of a mineral, solution, or another conductive material in the solution.
These devices are also helpful in automobiles to test the transmission of signals, resulting in a checked engine. In the electrical safety analysis, these trackers help in verifying the wearing connections on the primary power supply.
Eddy current meter is vastly used for fundamental research like in mass spectrometry, magnetic fields, and impedance spectrometry and to measure rare earth elements which happen to be observed in very dilute quantities within the water.
The meter can give readings between 0 and 600 micro siemens per centimetre (μS/cm) depending on the solution. It is used in mining, drilling, oil and gas, and chemical and food processing industries.

How does the Eddy Current Conductivity Metre work?
The Eddy Current Conductivity Meter works by using the principle of eddy currents. The EDC conductivity meter uses a probe to measure the material's conductivity upon contact.
The user must insert the probe into the material. Low-conductive materials and non-metallic such as glass, ceramics, rubber, and galvanized metal can not be measured by this device. The instrument's dual-frequency inverter upsets the sample underneath by ionizing water molecules. In some materials, there are fewer ions than in other materials.
These minimal accumulations will result in measuring inconsistency concerning metals. Glass jar would not respond appropriately in this regard, thereby making it unknown as to its conductivity above all else.
The instrument has several pre-programmed tested combinations that effectively readout of the material's response fused with internal current sensors.
Differential amplification between those two controllers leads to differences in measured properties within those conditions where similar-sized cuvettes were used for eddy current determination against each other.
To attain accurate results, spectrum analyzers should be used and correlated with data before discarding as erroneous measurements have been made in either system errors or instrumental contamination.
Conclusion
Through this piece, you could read up on the eddy current conductivity meter. The benefits are that it's easy to read, it cuts down on the labor of doing things by hand, and how to use of the test area could be impaired in working conditions where there is limited light due to dust or poor ventilation.
