Conductivity Sensors FAQs

What is Conductivity Sensor in water?

Water conductivity sensors are used in water-quality applications to measure how well a solution conducts an electrical current. … The more ions that are in the solution, the higher the conductivity

How does a Conductivity Sensor work?

How the Sensor Works. The Vernier Conductivity Probe measures the ability of a solution to conduct an electric current between two electrodes. In solution, the current flows by ion transport. Therefore, an increasing concentration of ions in the solution will result in higher conductivity values.

What is the principle of Conductivity?

Conductivity is the ability of a solution to conduct electric current. The principle by which instruments measures conductivity is simple – two plates (cells) are placed in the sample, a potential is applied across the plates and the current is measured. Generally, the potential is in the form of a sine wave.

Why do we measure Conductivity?

Conductivity measures the water’s ability to conduct electricity. … Common ions in water that conduct electrical current include sodium, chloride, calcium, and magnesium. Because dissolved salts and other inorganic chemicals conduct electrical current, conductivity increases as salinity increases.

What is the purpose of calibrating a Conductivity Sensor?

A solution’s conductivity is affected by the ions in solution and temperature. To measure conductivity, a conductivity sensor uses a probe with four electrodes. The sensor passes an alternating current between electrodes and measures the potential between the inner pair.
