Inline Conductivity Meter PTCond-m (high-range)

The PTCond-m High-Range Inline Conductivity Meter by PrismaTech is manufactured in Iran and is designed to measure the electrical conductivity of liquids to determine the concentration of electrolyte solutions.

Online conductivity meter, also known as an inline conductivity meter or EC meter, is used across various industries. The conductivity of liquids depends on four main factors: the concentration, the mobility of ions in the liquid, the interaction between ions, and the temperature of the liquid.

A key feature of the inline conductivity meter is its ability to measure the electrical conductivity of solutions in real-time during the process, as well as its capability for direct installation on pipelines (in-line).

By being installed directly on pipelines or tanks, it can measure the conductivity of a fluid as it flows through the system.

This model of inline conductivity meter can be used for applications such as measuring and controlling the conductivity and hardness of water in cooling systems, boilers, and power plants. It is also used for measuring conductivity during the production process of various edible and industrial salts. The PrismaTech inline EC meter model PTCond-m can be installed on pipes and tanks with a diameter greater than 10 centimeters.

Working principle of PTCond-m High-Range Inline Conductivity Meter

The online or inline electrical conductivity meter (EC meter) measures conductivity using a probe that applies an alternating electrical current to two or four electrodes. This process measures the electrical resistance of the solution. After immersing the electrodes in the solution, the device applies a voltage between them. The electrical resistance of the solution causes a voltage drop, which is then measured. When the electrical current is applied, positively charged ions (cations) move toward the negative electrode, and negatively charged ions (anions) move toward the positive electrode. This ion movement generates electrical conductivity in the solution.

Applications of the PTCond-m High-Range Inline Conductivity Meter

By measuring the conductivity of a solution, valuable insights can be obtained about the nature of the solution and the particles it contains. Measuring pH and conductivity are two key parameters in determining the acidity or alkalinity of solutions. Conductivity measurement is also one of the most important analytical measurements in many industrial processes.

This measurement is considered one of the least specific analytical techniques because it does not distinguish between different conductive substances dissolved in the solution. Therefore, conductivity measurement is used in processes where identifying the specific type of dissolved conductive substance is unnecessary.

For example, in the production of ultrapure water for semiconductor manufacturing, this method is used because the presence of any conductive material dissolved in the water is undesirable.

Another common application of conductivity measurement occurs when the only conductive material in the solution is known, such as in saltwater, where large amounts of salt are dissolved in water.
