Description
Compact copper sulfate reference electrodes should be purchased to perform measurements on underground metal structures. The device allows accurate measurements on pipelines of various purposes and steel structures.
The modernized reference electrode installation is used to determine the degree of protection against corrosion changes of metal structures located underground. Installation of the reference electrodes should be carried out directly in the soil above the inspected object. A mandatory condition is that the modernized reference electrodes are installed below the soil freezing depth.
The device conductors are routed to a special measurement control point or to a cover. ESMS.KMG-M-VE can be used as portable. The main advantages of the unit include long service life and non-polarizable properties. Inside the reference electrode housing there is a copper electrode; the inner chamber is protected from adverse effects by bentonite filling. Inside this chamber there is copper sulfate filling.
The unit is supplied fully ready for use. No additional operations are required to perform measurements. The cable length is not limited by the manufacturer and can be agreed with the customer. The final order price depends on this parameter. The reference electrode housing is made of durable, sealed material and withstands moderate loads and damage.
During operation of the modernized copper sulfate reference electrode, constant contact of the electrode with the soil is ensured. This is provided by an ion-exchange membrane. The configuration is supplemented with an auxiliary electrode (VE), which allows potential measurements. It is located in the lower part of the unit housing. If necessary, a model without VE can be ordered. For more convenient installation and subsequent maintenance, the model is equipped with information tags on the cables.
