WSRE-meter
Remote monitoring and mapping of corrosion probability in reinforced concrete Request informationWSRE-meter is an advanced technological solution designed for the remote and continuous, long-term assessment of corrosion status in reinforced concrete infrastructure. This system allows the generation of corrosion probability maps in large areas, effectively identifying active or passive areas without requiring destructive interventions in the concrete.
Based on the technology of Solid State Reference Electrode from Witeklab, the WSRE-meter ensures a superior metrological stability in measuring corrosion potential. The system provides continuous access to reliable information from local or remote servers, making it an essential tool for initial diagnosis and optimization of preventive maintenance strategiesy la optimización de las estrategias de mantenimiento preventivo.
Non-destructive diagnostics
Assessment of the condition of the armor and determination of the probability of corrosion while preserving structural integrity.
Comprehensive remote monitoring
Telematic data management, monitoring of historical trends and configuration of alarms through a web platform.
Electrochemical stability
Solid electrode technology that guarantees constant measurements, independent of temperature and free from drift or risk of contamination.
Potential mapping
Spatial representation of active and passive areas through the generation of surface or depth potential maps.
Regulatory compliance
Results aligned with international standards such as ASTM C876 and UNE-EN 1504-9.
Cost efficiency
WSRE-meter enables high-density monitoring, maximising the spatial coverage of the analysis..
Proactive management of structural risks
WSRE-meter is a superior solution for monitoring corrosion over large areas, early detection of vulnerable zones, and tracking long-term potential trends, thanks to its unique features:
High-density monitoring
WSRE-meter redefines the structural diagnostic strategy. Its cost-effectiveness allows for the deployment of a dense network of sensors, overcoming the limitations of point sampling. This approach prioritizes the spatial identification of risks across multiple locations, optimizing monitoring coverage.
Real-time corrosion mapping
By strategically placing electrodes at varying depths and distances, the system generates potential maps that distinguish between passive zones and active areas at risk of oxidation or local activation (pitting, chlorides). This functionality allows for comparative analysis between different points of the structure and validates the effectiveness of protective measures or cathodic protection (CP) systems.
Reliability based on chemical stability
The core of the system is the Stable Reference Electrode W-S-RE unlike conventional (Ag/AgCl) electrodes, which are susceptible to temporary drift, this solid-state technology maintains a constant ionic concentration and zero thermal dependence. This ensures that the recorded variations correspond exclusively to real changes in the electrochemical state of the structure, and therefore the potential measurement is highly stable.
Technical and regulatory compliance
The WSRE-meter operates by quantitatively measuring corrosion potential (Ecorr), a repeatable physical parameter based on the free energy of the metal system. More negative values indicate reducing conditions or the presence of cathodic protection, while more positive values indicate a risk of active corrosion or oxidation..
This methodology adheres to the technical recommendations of Model Code 2010 (fib) and RILEM TC 154-EMC, allowing the application of the corrosion probability criteria established in the ASTM C876 standard. Furthermore, it provides a result that can be referenced to the UNE-EN 1504-9 standard, which includes the use of electrochemical methods in diagnosis.
