    Q1: What is a conductivity meter?

    The conductivity meter is mainly an instrument for measuring the current capacity of the liquid medium. They are generally used for continuous monitoring of conductivity values in electric power, the chemical industry, metallurgy, environmental protection, pharmaceuticals, fields, lakes, scientific research, food and tap water, as well as in water treatment and aquaculture experiments.

    Q2: How does a conductivity meter work?

    Conductivity Meter Principle Conductivity is a numerical representation of the ability of a solution to conduct electrical current. The conductivity of water has a certain relationship with the number of inorganic acids, alkalis and salts contained in the water. When their concentrations are low, the conductivity increases with the increase of the concentration. Therefore, this indicator is often used to infer the total concentration or salinity of ions in water. Conductance (G) is the inverse of resistance (R). As a result, when two electrodes (usually platinum or platinum black) are inserted into the solution, the resistance R between the two electrodes can be measured. According to Ohm's law, the resistance value is proportional to the electrode spacing L (cm) and inversely proportional to the electrode's cross-sectional area a (cm2 ).

    Q3: What is a conductivity meter used for?

    • Water quality monitoring: The conductivity is affected by salt, inorganic acid, alkali, etc. in the water, so the higher the conductivity, the higher the concentration in the water will be reflected, the total concentration and salt content of ions in the water can be understood, and the purity of the water quality and due to the control of the production process, the conductivity of the water will vary with the TDS content in the water.
    • Electroplating solution: Conductivity is an important parameter reflecting the electroplating solution. It can reduce the voltage in the electroplating bath and improve the dispersion ability of the electroplating solution. The conductivity of the electroplating solution can be reflected by measuring the conductivity.
    • Atmospheric monitoring: The conductivity meter is used in atmospheric monitoring mainly for pollutants contained in the atmosphere such as carbon monoxide, sulfur dioxide, carbon dioxide and various nitrogen oxides. It can pass the gas absorption device and pass the gas through the absorption liquid to check the change of conductivity and monitor exceeding the standard in the polluted area

    Not perfect
    The Water Conductivity Meter with a 200mS/cm rating and DC 9V power source is a reliable tool for water quality testing. It offers accurate measurements within a wide range, and its battery-powered feature adds portability. However, you'll need to be mindful of calibration and handle it with care due to its somewhat delicate nature.
