REFERENCE ELECTRODE MANUFACTURER
Reference Electrodes for Cathodic Protection Monitoring
Ag/AgCl, Cu/CuSO₄, MnO₂ and zinc reference electrodes for field cathodic-protection monitoring in marine, soil, tank and reinforced-concrete environments.
Reference-electrode chemistry must match the environment and measurement basis. Potential values are meaningful only with the comparison scale, temperature, electrolyte, tolerance and calibration conditions.

PRODUCT DEFINITION
Select the Reference Electrode by Environment and Measurement Task
A reference electrode provides a stable comparison potential for measuring structure-to-electrolyte potential or controlling a cathodic-protection system. Field reference electrodes are not interchangeable with laboratory reference cells. Chemistry, housing, junction, cable, installation, stability and conversion basis must be selected for the actual environment.
Product Boundary
The page is a field-CP product category, not a laboratory electrochemistry guide. Detailed chemistry-specific terms should resolve to the four child product pages.

Parameters to Confirm Before Purchase
Values without a comparison basis, test method or operating condition are not directly comparable. Unverified values must remain subject to application review.
| Chemistry and environment | Ag/AgCl, Cu/CuSO₄, MnO₂ or zinc selected for seawater, soil, concrete or the approved application. |
|---|---|
| Potential basis | Potential value, comparison electrode, electrolyte concentration and temperature stated together. |
| Tolerance and stability | Initial tolerance, drift or stability acceptance and test duration defined by the project. |
| Temperature | Operating range and temperature coefficient where verified and required. |
| Housing and junction | Body material, porous junction, package, backfill or embedment interface. |
| Cable and gland | Cable type, cross-section, length, insulation, gland, connector and sealing. |
| Life and maintenance | Service-life basis, storage, wetting, inspection and replacement conditions. |
| Documents | Calibration or acceptance record, drawing, installation guide and traceable product documentation. |

QUALITY AND DOCUMENTATION
Tie Every Claim to an Acceptance Basis
The drawing, material or chemistry, dimensions, electrical interface, cable sealing and acceptance test should be controlled by the purchase specification and agreed ITP.
Performance statements must identify the comparison scale, environment, temperature, duration and method. Service life remains conditional on installation and operating conditions.
Documents by Agreed Scope
• Approved drawing• Material or batch record• Dimensional inspection• Electrical checks• Calibration or acceptance data• Installation guidance• Marking and traceability• Packing record

FAQ
Technical and Procurement Questions
How do I confirm that this is the correct product?+
Match the product chemistry and construction to the protected asset, environment, measurement or protection task, operating conditions, installation interface and governing specification.
Which values need test conditions?+
Potential, tolerance, stability, drift, temperature coefficient, current output or service life must be tied to the applicable comparison scale, electrolyte, temperature, duration and method.
Can the assembly be customized?+
Housing, dimensions, cable, connector, thread, backfill, package, mounting and documentation can be reviewed against the approved drawing and validation scope.
What documents can be supplied?+
Depending on the purchase order, available records may include approved drawings, material or batch records, dimensional inspection, electrical checks, calibration or acceptance data, marking and packing.
Who is responsible for final system design?+
HELE can review product manufacturability and stated supply scope. The project parties must define responsibility for system design, installation, commissioning, calibration, maintenance and final compliance.
What should be included in the RFQ?+
Provide the protected structure, environment, monitoring or control purpose, expected comparison scale, temperature range, installation depth or pressure, housing and junction requirements, cable type and length, calibration or acceptance criteria, quantity and drawings.
