A conductivity meter is an instrument used to measure the ability of a solution to conduct an electrical current. It measures the conductivity of a solution in terms of electrical conductance, which is the reciprocal of the solution's resistance. Conductivity meters are used to measure the purity and concentration of a solution, as well as to monitor the progress of chemical reactions.
Conductivity meters consist of a probe and a meter, which work together to measure the electrical conductance of a solution. The probe is inserted into the solution and uses two electrodes to measure the electrical resistance of the solution. The meter then calculates the electrical conductance of the solution based on the resistance measurement.
Conductivity meters are commonly used in a variety of industries, including water treatment, agriculture, food and beverage production, and pharmaceutical manufacturing. They are used to measure the conductivity of solutions such as drinking water, irrigation water, milk, and pharmaceutical solutions. They are also used to monitor the quality of chemical reactions in laboratory settings.
Conductivity meters can be either portable or benchtop models. Portable models are designed for on-site testing and are often battery-operated. Benchtop models are designed for laboratory use and are often more precise and accurate than portable models. Some models also have additional features, such as the ability to measure temperature or to automatically compensate for temperature changes.
