動作原理
The water conductivity sensor working principle: when the conductivity electrode is in the solution, the electrode is equivalent to resistance, and the size of the resistance is inversely related to the conductivity of the solution. When the conductivity of the solution is fixed, the resistance of the electrode is proportional to the electrode constant K. Inverse relationship. Therefore, the measured value of the conductivity of the solution is calculated based on the resistance of the electrode and the constant K of the electrode itself and is obtained through temperature compensation.

FAQs - Water Conductivity Sensor
Conductivity refers to the ability to conduct current in a body of water. In water quality monitoring, conductivity is one of the important indicators reflecting the quality of water quality. When the conductivity value of the water is higher, the conductivity is better, and the TDS value in the water is larger. The TDS value represents the content of dissolved impurities in the water. The larger the TDS value, the higher the impurity content in the water. On the contrary, the smaller the impurity content, the higher the water Pure, the lower the conductivity.
The conductivity of water can be measured with a conductivity detector. Put the conductivity probe into the water. Calculate the conductivity value by measuring the change in solution resistance.
Water conductivity sensors are used in water-quality applications to measure how well a solution conducts an electrical current. This type of measurement assesses the concentration of ions in the solution. The more ions that are in the solution, the higher the conductivity.
In normal use, the electrode will not be scratched or corroded and can be used all the time. If the electrode is damaged, the measurement accuracy will be affected, and the electrode needs to be replaced in time.
The temperature compensation of conductivity is to compensate the conductivity value at the current temperature to the conductivity value at the specified temperature (default 25°C). The temperature coefficient is the percentage value of the change in the conductivity of the solution with the temperature, and the percentage change in the conductivity when the temperature rises by 1℃. The default 0.02 (2%) approximates the temperature coefficient of conductivity of potassium chloride solution. The user can set the temperature coefficient value by himself to make the temperature compensation more accurate. The method is to first set the temperature compensation coefficient of the device to 0, and then measure the conductance in the same solution to be tested at two different temperatures (t1, t2) Rate value (g1, g2), and then use the formula to obtain the change in conductivity per 1°C increase Δg=(g1-g2)/(t1-t2), and then measure the conductivity of the solution under test at 25°C, g0 , The temperature coefficient can be calculated as: α= Δg/g0.
It is recommended to calibrate with a standard solution close to the conductivity value of the solution to be tested. If the conductivity value of the solution to be tested is not clear, select a standard solution close to the middle value of the range.
- Under normal conditions, the sensor itself does not require routine maintenance. If a clear malfunction occurs, do not open or attempt to repair the sensor yourself. Please contact us as soon as possible.
- Before use, gently shake the conductivity electrode in the sample liquid to remove any air bubbles attached to the electrode surface. The measurement can then be performed normally.
- When the electrode is not used for a long period, it can generally be stored in a dry place. However, before reuse, it must be immersed in distilled water for several hours to activate the electrode. Electrodes that are used frequently may be stored in distilled water.
- Organic contamination on the electrode can be cleaned with warm water containing a mild detergent, or with alcohol. Calcium and magnesium deposits are best removed using a 10 percent citric acid solution.
- The electrode plates or pins should only be cleaned by chemical methods or by gently agitating them in water. Do not wipe the electrode plates or pins, as this may damage the platinum black coating on the electrode surface.
- The device should be calibrated before each use. For long term operation, calibration every three months is recommended. The calibration frequency should be adjusted according to application conditions, such as the level of fouling and chemical deposition.
- Do not immerse the cable connector in water before it is fully locked to the instrument connector.
For instruments with an electrode constant K = 1 and a measurement range of 1 to 10,000 μS/cm, use a 12,880 μS/cm standard solution for calibration.
For instruments with an electrode constant K = 10 and a measurement range of 1 to 100,000 μS/cm, use a 111,310 μS/cm standard solution.
During calibration, place the electrode into the standard solution after it has returned to room temperature. Gently agitate the electrode to speed up the response. Make sure the sensing section of the electrode is fully immersed in the solution and that no air bubbles are attached to the electrode surface. Then allow the system to stand still.
Once the conductivity reading has stabilized, adjust the electrode constant K according to the following formula:
Electrode constant K = (standard solution value ÷ current reading) × current electrode constant
The calibration is then complete.
It is recommended to use plastic conductivity electrodes for non-corrosive water, such as: hydrological observation, water plant treatment, aquaculture, etc.
It is recommended to use stainless steel conductivity electrodes for corrosive water, such as environmental protection pharmaceuticals, food processing, sewage treatment, etc.
- Submerged installation: the lead wire of the electrode passes through the stainless steel tube, and the 3/4 thread on the top of the electrode is connected with the stainless steel 3/4 thread with raw material tape. Make sure that no water enters the top of the electrode and the electrode wire.
- Pipeline installation: connect to the pipeline through the electrode 3/4 thread.
Our water conductivity sensor has been calibrated before leaving the factory. If you need to calibrate it later, you can find a solution with a known conductivity to calibrate it yourself. In the case of long-term use, it is best to calibrate once every three months.
Under normal conditions, the electrode has a one-year warranty and the data collector has a two-year warranty.
