  (4)The electrode structure is firm,Joint corrosion resistance,The leakage rate of microporous membrane is appropriate,No visible liquid flow,Can be placed in the pocket。

3、Use and maintenance of copper sulfate reference electrode

      First, the surface of the reference electrode should be kept clean,When not in use,Cover the multi hole plug with plastic bag or rubber cap,Avoid contamination。Then replace the copper sulfate inside regularly,And clean the rod with non-metallic abrasive materials;for example,Use silica sandpaper instead of alumina sandpaper to clean the copper bar,If the solution becomes turbid,Pour it out and replace it with a new copper sulfate solution。Ensure that there are still undissolved crystals in the solution;This saturated copper sulfate solution can prevent copper corrosion,So that the electrode is stable。In a polluted environment,After using the electrode,To maintain it。Contamination of chlorinated compounds can change chemical reactions。When the concentration is5pptWhen,Reference potential becomes yes-20mVMixed potential of deviation,The concentration is100pptWhen,Deviation reaches-95mV。During the construction of cathodic protection project,A reference electrode should be prepared for standby,If the electrode is lost,Then another reference electrode can be used to continue working。 

       When the reference electrode is used on site, another new electrode needs to be prepared,In order to calibrate whether the electrodes used on site are accurate。However, when the value measured by the calibration electrode is more than the value measured by the reference electrode being used on site5mVWhen,It is necessary to clean the electrodes used on the construction site。 

       Because of the temperature in the construction environment、The sunlight is different,Therefore, it is necessary to correct the change of potential。Potential correction for different temperatures,It is necessary to record the temperature while reading the value of the reference electrode。When the reference temperature value used is higher or lower than the actual temperature value,Be sure to add or subtract separately when recording0.5mV/°Fperhaps0.9mV/°CTemperature correction value of。 

       Shielding electrode is required in the measurement process of using reference electrode,Avoid direct sunlight,The transparent part on one side of the electrode can be covered with black tape。Different degrees of sunlight exposure,The value measured by the reference electrode will also be different,The potential of the reference electrode in a sunny environment is higher than that in a dark place without sunshine10reach50mV。 

       In a special environment, the reference electrode should also choose different types according to different environments,Such as the special reference electrode on the inner wall of the storage tank,It is used for the measurement of cathodic protection potential in the inner wall of storage tank or other water medium。The structure of this special reference electrode is to fix the pure zinc rod in a porous non-metallic shell,Ensure that the electrode does not have direct contact with the protected equipment。The potential of the special reference electrode on the inner wall of the storage tank is in the sleeve,To avoid direct contact with the wall,Electrode potential is-1.10V CSE,Potential stabilization,Drift or polarization less than5%,The structure protection potential should be lower than+0.25V。The main components of the special reference electrode on the inner wall of the storage tank are:A1less than0.005%,Cdless than0.003%,Feless than0.0014%,Culess than0.002%,Pbless than0.003%,ZnIs margin。1.Application of portable reference electrode: Portable copper sulfate reference electrode is suitable for field use。It is mainly used to measure the natural potential and cathodic protection potential of underground metal pipelines,Determination of stray current in soil,It can also be used to measure the potential of cable metal sheath and reinforcement in concrete。The electrode is in the place with sticky soil,It can be used as a reference electrode for controlling potential in impressed current cathodic protection system。It can be used in all kinds of soil and fresh water。
