This is achieved due to the fact that the portable non-compromised copper-sulphate reference electrode consists of a housing 1 with a hydrophilic bottom 2 and an airtight lid 3. Moreover, the housing 1, in which a saturated solution 6 of copper vitriol is placed, is made in the form of a copper cylinder, on the top the side surface of the case is located

The invention relates to the electrochemical protection of metals against corrosion and can be used in all areas of the national economy to determine stationary corrosion potentials and protection potentials.

The aim of the invention is to simplify its manufacturing technology, increase reliability and expand the scope of use by using it to measure the potential difference of the protected object - water.

The drawing shows the design of the proposed electrode.

The electrode contains a copper case 1c one 2 of a hydrophilic material (wood, membrane), a hermetic cover 3, and a contact element 4 for connecting the measuring conductor. The outer surface of the housing 1 is covered with an insulating polymeric material 5. In the upper part of the housing 1 in the material 5 there is a cutout for attaching the contact element 4 to the surface of the housing 1.

The saturated solution of copper sulphate is poured into the housing 1, and an electrode reaction takes place. The housing 1 is closed with an airtight cover 3, the measuring conductor from the minus-voltmeter minus terminal is connected to the element 4, where the positive terminal is connected to the metal, and the electrode is placed at that point of the electrolyte (soil) that has the contact conductor 4 the surface of the body is insulated with a polymeric material 5. The copper body 1 simultaneously performs the role of a core and a body. Due to this, the dimensions of the electrode are reduced, the number of its elements is reduced, and the current efficiency is increased. 1 ill., 1 tab.

shorter distance to the metal surface, and the electrode is ready for operation.

The table shows the technical parameters of the reference electrodes.

It follows from the table that the proposed portable non-charge-resistant copper sulphate reference electrode has the following advantages: the current strength is higher, the current output is 2 times higher, the mass is 2 times smaller, the diameter is 3 times smaller, the number of elements is reduced.

The copper casing simultaneously performs the role of a core and a casing. Due to this, the dimensions of the electrode are reduced, the number of its constituent elements is reduced, and the current efficiency is increased.
