Portable copper sulfate reference electrode Executive Standard: GB / T 7387-1999 1, the main performance: small size, easy to carry; electrode potential stability, electrode polarization is not easy, long service life. Scope: suitable for field use, mainly for the determination of potential natural potential and cathodic protection of underground metal pipes, measuring soil stray current can also be used to determine the potential of the cable metal sheath and concrete reinforcement. 2, the product features a portable copper sulfate reference electrode suitable for use in the field. Mainly used to determine the potential of natural potential and cathodic protection of underground metal pipes, measuring soil stray current can also be used to determine the potential of the cable metal sheath and concrete reinforcement. The electrodes in the soil than the sticky places, for impressed current cathodic protection system in the control potentiometer with a reference electrode. Can be used in all types of soil and fresh water. 3, the structure and properties of (1) the electrode small, easy to carry. Cavity by the ABS or transparent plexiglass tubes, to observe the inside to facilitate saturation of the copper sulfate solution. (2) stable electrode potential, electrode polarization is not easy. (3) long electrode life, the electrode cap is connected to the electrode cavity with a screw for easy filling solution. Irrigation fluid can be used more than once a year. (4) electrode structure strong, corrosion-resistant joints, microporous membrane leakage rate expedient, no visible flow, can be placed in your pocket.
