Reference electrodes play a key role in cathodic protection systems designed to prevent corrosion of underground steel pipelines and structures.

Their application is based on the ability to measure polarization and total potentials, which makes it possible to effectively monitor and maintain optimal conditions of electrochemical interaction.

PES-01-(K)-G-VE portable copper sulfate reference electrodes with an auxiliary electrode provide accurate potential data on corrosion-prone facilities (oil and gas pipelines), which is critical for assessing the effectiveness of the protection system.

Regular monitoring of polarization potential helps prevent undesirable electrochemical reactions, contributing to the preservation of the integrity of steel pipeline lines and underground facilities.

Reference electrodes are an integral part of infrastructure. Their use helps extend service life and increase the efficiency and reliability of transport systems and structures under underground operating conditions.

Our company offers PES-01-(K)-G-VE portable copper sulfate reference electrodes with an auxiliary electrode, non-polarizable and long-life, specifically designed for use in soil at depths exceeding the soil freezing level. The conductors can be routed to a cover or to a test point (KIP).

Advantages

PES-01-(K)-G-VE portable copper sulfate reference electrodes with an auxiliary electrode are ready for use and do not require additional preparation or electrolyte filling.

The reference electrode is placed in a durable container made of material resistant to mechanical damage.

Efficiency is achieved through capillary channels of the outer ceramic membrane with standardized porosity, through which electrolytic contact is formed. This ensures stable operation over a long period.

The cable length is not regulated and can be any. The customer determines the required cable length for the facility.

The advantage of using a bentonite chamber in PES-01-(K)-G-VE portable copper sulfate reference electrodes with an auxiliary electrode is the prevention of mutual diffusion of electrolyte between the electrode and the soil. This ensures stability and efficiency over long-term operation.

One of the important parameters is spreading resistance, which is at least 5 kΩ.

The potential relative to a laboratory silver/silver chloride reference electrode is 100±20 mV, indicating the accuracy and reliability of measurements performed using this system.

The devices operate for up to 30 years or more.

The weight of the device, excluding cable outlets, does not exceed 2.5 kg, which makes it convenient and cost-effective for transportation and installation.

Modernized copper sulfate reference electrodes of the MES-02-(P-K)-G-VE-M model are stationary. They are installed directly above the metal structure. The reference electrode is buried in the soil to a level below the soil freezing depth. Measurements performed using the device comply with GOST requirements.

The outer housing of the reference electrode is made of porous ceramic, which increases its service life. The material ensures stable operation of the unit in different soil types. The inner housing is surrounded by bentonite filler, which provides moisture retention. A spiral electrode made of pure copper is immersed in copper sulfate. This model can be ordered with measuring cables with a length of at least 2 meters.

The use of the auxiliary electrode allows measurements to be performed using the polarization current interruption method. The cables are equipped with terminals for convenient connection. Marking information tags on the cable outlets allow easier maintenance and operation of the unit.

Modernized copper sulfate reference electrodes consist of:

• outer and inner housings;
• bentonite filler;
• measuring cable;
• heat-shrink sleeve;
• cable lug.

Depending on the cable length selected by the customer, the final order price may vary.

Product characteristics

Reference electrodes can be used in different soil types (arid, saline, etc.). The measuring cable in the device is load-bearing and is used for installation of the electrode.

The MES-02-(P-K)-G-VE model has its own features – it is a double-housing device. The outer ceramic housing is intended to create and maintain electrolytic contact during measurements. The porous ceramic is sufficiently strong and capable of withstanding moderate mechanical воздействия. Inside it there is a measuring module. This is the second housing filled with copper sulfate. The reference electrode is located in it. The space between the housings is filled with a moisture-retaining substance.

To measure the polarization potential, the device is equipped with an auxiliary electrode. The VE is located in the lower part of the housing and is connected to terminals. Marked cables are routed from the main and auxiliary electrodes. The information tags are intended for more convenient operation and maintenance of the reference electrodes. Stationary copper sulfate reference electrodes with an auxiliary electrode (VE) can be ordered for performing measurements in arid regions.

The double-housing reference electrode includes in its design:

• measuring module;
• outer and inner housings;
• moisture-retaining filling;
• auxiliary electrode and cable;
• heat-shrink sleeve.

The device can be operated at temperatures from 0 to +55 degrees Celsius.

Product characteristics

The copper sulfate reference electrode is supplied with cable outlets with a length of at least 2 meters. When placing an order, the required cable length can be specified. The final price of the product depends on this parameter.

They are installed in the soil, with the depth determined by the laying level of the metal structure. The conductor is routed to a cover or to KIP; they can also be used as portable. The products are considered non-polarizable and have a long service life.

Product characteristics

The manufacturer ensures that stationary reference electrodes MES-01-(K)-G-VE-M are fully ready for operation. The operating organization does not need to prepare or fill the electrolyte in the future. The product has the following characteristics:

• Service life – from 30 years;
• Spreading resistance – up to 5 kΩ;
• Potential relative to a laboratory silver/silver chloride reference electrode – 100 mV with an accuracy of ±20;
• Cable outlet length – not less than 200 cm;
• Weight – not more than 2500 g.

To ensure the housing is sealed, materials with high impact resistance are used. The ceramic membrane with standardized porosity contains capillary channels that provide electrolytic contact with the soil. The length of the connecting cables is determined according to customer requirements. Mutual diffusion of the electrode electrolyte and the soil electrolyte is prevented by the presence of a special bentonite chamber. MES-01-(K)-G-VE-M can be ordered on our website with delivery.

• Service life – from 30 years;

They are installed in any type of soil at a depth associated with the laying of underground metal structures. The installation depth is below the soil freezing level, with routing of conductors through a cover or to KIP; they can also be used as portable. This electrochemical system is considered non-polarizable and provides the longest service life.

Product characteristics

The manufacturer ensures full readiness for future use. Due to its composition, no preparation or filling of a special electrolyte is required when using this electrochemical system. The sealed housing has an impact-resistant design made of suitable materials. Copper sulfate reference electrodes can be ordered on our website at optimal prices.

Electrolytic contact with the soil is provided by capillary channels with an external ceramic membrane having standardized porosity. The length of the connecting cables is determined according to the customer’s requirements. The use of a bentonite chamber prevents mutual diffusion of the two media – the electrode electrolyte and the soil electrolyte.
