WEC1200C Conductivity/Hardness/Resistivity Online analyzer, an intelligent online chemical analyzer, is frequently used in the thermal power, chemical fertilizer, environmental protection, metallurgy, pharmacy, biochemistry, food, and water industries for continuous monitoring and measurement of EC value, TDS value, or ER value, and temperature in the solution.
EC / TDS Transmitter Calibration
Calibrating a conductivity transmitter involves several key steps to ensure accurate measurements. First, gather the necessary equipment, including the transmitter, standard conductivity solutions (such as 84 µS/cm and 1413 µS/cm), calibration beakers, a thermometer, and deionized water for rinsing. Begin by turning on the transmitter and allowing it to warm up, ensuring that any temperature compensation settings are correctly adjusted. Clean the electrode with deionized water to remove any contaminants, and immerse it in the first standard solution. Once the reading stabilizes, adjust the transmitter to match the known conductivity value of the solution. After rinsing the electrode, repeat the process with additional standard solutions if multi-point calibration is needed. Verify the accuracy of the calibration by rechecking the readings against the standards.

A tool for determining a solution’s electrical conductivity is a conductivity sensor. It is often utilized in many different sectors, including water treatment, food & beverage, and medicines. The sensor measures a solution’s capacity to carry an electrical current. To do this, submerge two electrodes in the fluid and briefly apply voltage between them.
The concentration of dissolved ions in a solution is directly correlated with its conductivity. As a result, the sensor may be used to measure the concentration of several ions, including calcium, sodium, and chloride. Numerous variables, like the solution’s purity and temperature, affect the sensor’s accuracy.
