Description

The МЭС-02-(П-К)-(Г-Т)-ВЭ-М is a stationary long-service copper sulfate reference electrode produced by PROMTEHMASTER LLC (ООО НПК "ПромТехМастер") for electrochemical corrosion protection systems safeguarding buried metal infrastructure. Its dual-membrane architecture sets it apart: the inner housing holds a spiral of pure refined copper immersed in a gel-saturated copper(II) sulfate solution, while the outer chamber is filled with a bentonite clay-based contact electrolytic mass that retains moisture and maintains reliable soil contact even in high-resistivity, seasonally dry ground conditions where single-electrolyte electrodes become unreliable.

The ceramic ion-exchange membrane at the contact node provides a stable, low-resistance electrolytic path to soil, meeting the strict requirements of GOST 9.602-2016, which mandates verified protective polarized potential on all buried metal structures. The integrated auxiliary electrode (ВЭ) enables direct, simultaneous measurement of both polarization and total potential without additional instrumentation.

The electrode potential relative to a silver-chloride reference electrode is 100 ± 20 mV. The sealed mineralized impact-resistant polymer housing is rated for continuous service from −10 °C to +45 °C (climatic category O, placement category 5 per GOST 15150), with a design service life of at least 10 years.

The unit ships fully assembled and ready to install; cable leads of customer-specified length (minimum 3 m) arrive pre-labeled and pre-fitted with terminals for immediate connection to measurement control points (КИП) or inspection pits.

Details & Equipment

Product Views

Assembled Electrode Unit

The МЭС-02-(П-К)-(Г-Т)-ВЭ-М ships fully assembled in its sealed mineralized polymer housing. Cable leads are pre-labeled with identification tags and fitted with terminals for direct connection to measurement control points.

Housing and Cable Assembly

The compact electrode body houses the inner copper electrode, gel-saturated copper sulfate fill, and ion-exchange membranes. The auxiliary electrode cable (ВЭ) exits alongside the main measurement conductor, both pre-terminated.

Model Designation Chart

The ПТМ-МЭС designation chart decodes each element of the model code: П/К denotes the outer contact node type, Г-Т indicates the combined gel-and-solid electrolyte fill, ВЭ confirms the auxiliary electrode, and М marks the modernized configuration.

Features

🔬

Dual-Membrane Design

Combines a gel-saturated copper sulfate inner chamber with a solid bentonite electrolytic outer mass, separated by a ceramic ion-exchange membrane of normalized porosity for precise, stable measurement.

⚡

Integrated Auxiliary Electrode

The built-in auxiliary electrode (ВЭ) allows simultaneous measurement of both polarization potential and total protective potential in a single installation, as required by GOST 9.602-2016.

🌱

Bentonite Moisture-Retaining Fill

The outer housing is packed with bentonite clay-based contact electrolytic mass that holds moisture and maintains stable soil contact in high-resistivity or dry soil conditions where conventional electrodes fail.

🏗️

Impact-Resistant Polymer Housing

The sealed mineralized polymer body withstands moderate mechanical loads and long-term burial conditions, rated for climate category O, placement 5 per GOST 15150 from −10 °C to +45 °C.

📦

Ready-to-Install Delivery

The electrode arrives fully assembled with no field preparation required; cable leads are pre-labeled and pre-fitted with КИП terminals, and cable length can be specified at order time.

⏱️

Long Service Life

Designed for at least 10 years of continuous underground service, with gel electrolyte formulation and bentonite fill ensuring consistent electrode potential stability throughout the operating life.

Buyer Benefits

Measures polarization and total protective potential simultaneously in one unit, eliminating the need for separate instrumentation
Stable electrode potential of 100 ± 20 mV relative to silver-chloride reference maintained throughout service life
Reliable operation in dry, high-resistivity soils due to moisture-retaining bentonite outer electrolytic mass
Fully compliant with GOST 9.602-2016 requirements for underground metal structure protection verification
Operates across −10 °C to +45 °C without additional winterization measures (GOST 15150 category O/5)
Custom cable length agreed at order — pre-labeled and terminated conductors reduce installation errors
Minimum 10-year design life lowers total cost of ownership versus more frequent replacement cycles

Applications

Cathodic protection monitoring of buried oil and gas transmission pipelines Corrosion surveillance of underground water supply, heating, and district energy networks Long-term protection monitoring of buried steel structural foundations and piled supports Measurement at inspection and control points (КИП) along pipeline right-of-way Electrochemical protection of underground storage tanks and vessel farms Corrosion protection verification for municipal utility corridors and cable ducts Installations in high-resistivity or seasonally dry soil zones where gel-only electrodes are unreliable Compliance testing and commissioning of cathodic protection systems per GOST 9.602-2016
