Measurement environment
Start with the actual electrolyte or concrete environment: soil, seawater, submerged asset or embedded concrete.
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.
Application fit
For field cathodic-protection monitoring, choose the reference-electrode chemistry and construction for the service environment. The individual product options below show the relevant installation interfaces.
Before requesting a quote
Define the Measurement Basis and Installation
Select a reference electrode by the monitoring environment, measurement task and installation arrangement. Potential values are meaningful only with the electrode chemistry, comparison scale and test conditions stated.
Electrode chemistry
Choose Ag/AgCl, Cu/CuSO₄, MnO₂ or zinc from the approved CP monitoring basis; they do not have interchangeable potentials.
Installation interface
Define permanent or accessible mounting, housing, junction, cable route, connector and exposure conditions.
Acceptance evidence
State the comparison electrode, conditioning, temperature, tolerance, drift method and documentation needed at handover.

Manufacturing & Supply Scope
What HELE Can Configure, Test and Document for Monitoring Projects
HELE can review a reference-electrode requirement against the electrolyte, measurement task, reference chemistry, installation, housing, cable and acceptance method. The ordered configuration and test basis determine what can be demonstrated before release.
01 · Measurement Review
Define the Reference Basis
Review the electrolyte, monitoring objective, expected potential range, temperature, service duration and permanent or portable duty.
Typical order output: Measurement basis and open application questions.
02 · Electrode Chemistry
Select the Appropriate Reference System
Match Ag/AgCl, Cu/CuSO₄, MnO₂ or zinc configurations to the approved environment and measurement task.
Typical order output: Order-specific chemistry and construction direction.
03 · Mechanical Construction
Configure Housing and Interface
Define body materials, porous interface, dimensions, pressure or immersion duty, mounting and installation protection.
Typical order output: Approved construction and dimensional basis.
04 · Cable & Connection
Control the Measurement Path
Specify cable type and length, termination, sealing, junction box, shielding or protection and site connection details.
Typical order output: Cable and installation interface schedule.
05 · Acceptance Testing
Verify the Agreed Electrode Boundary
Apply the specified visual, dimensional, electrical, potential, stability or calibration-related checks under stated conditions.
Typical order output: Acceptance data tied to method and environment.
06 · Documentation
Release Traceable Product Records
Coordinate drawing, material or batch record, inspection, test data, installation guidance, marking and packing as ordered.
Typical order output: Order-specific document and traceability package.
Responsibility Boundary
Define What Is Included Before Order Release
A reference electrode is one part of a measurement chain. Its acceptance does not guarantee the complete monitoring or control system, installation quality, field potential interpretation or long-term site performance.
Order rule: only the signed quotation, approved drawings, equipment or material schedule, inspection plan and responsibility matrix define the final HELE supply.
Before Requesting a Quote
Define the Measurement Basis and Installation Before Quotation
A reference electrode is part of a measurement chain. Select it against the electrolyte, reference chemistry, temperature, installation, cable system, stability requirement and acceptance method.
- State the electrolyte, reference chemistry and expected temperature range.
- Define the measurement objective and expected potential range.
- Confirm permanent, portable, laboratory or field installation duty.
- Specify housing, porous interface, cable, junction box and mounting details.
- Align calibration, stability, traceability and acceptance evidence.
Do not release a purchase order with only:
- A reference-electrode name with no electrolyte or installation duty
- A potential value quoted without its reference scale and temperature
- Laboratory performance applied directly to permanent field service
- Cable length, junctions and installation effects ignored
- The electrode treated as a guarantee for the complete monitoring or control system
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.
