　　Product type: portable copper sulfate reference electrode

　　Implementation standard: GB/T467-1997

　　Main performance: small size, easy to carry; The electrode potential is stable, the electrode is not easy to polarization, and the service life is long.

　　Scope of application: Suitable for field use, mainly used for measuring the natural potential and cathodic protection potential of underground metal pipeline, measuring stray current in soil, can also be used for measuring the potential of cable metal sheath and reinforcement in concrete.

　　Detailed introduction:

　　The portable copper sulfate reference electrode is suitable for field use. It is mainly used to measure the spontaneous potential and cathodic protection potential of underground metal pipelines, and the stray current in soil. It can also be used to measure the potential of metal sheath of cables and steel bars in concrete.

　　The electrode can be used as a reference electrode for potential control in impressed current cathodic protection system in sticky soil. It can be used in all kinds of soil and fresh water.

　Structural performance:

　　1, the electrode volume is small, easy to carry. The cavity is composed of transparent plexiglass or ABS tube for easy observation of the saturation of the copper sulfate solution inside.

　　2, the electrode potential is stable, the electrode is not easy to polarization.

　　3, the electrode life is long, the electrode cap and the electrode cavity are connected with the screw mouth, easy to fill the solution. One irrigation can be used for more than a year.

　　4, the electrode structure is firm, the joint is corrosion-resistant, the microporous membrane leakage rate is suitable, no visible liquid flow, can be placed in the pocket.
