Witeklab Stable Reference Electrode (W-S-RE)
Request informationThe most suitable reference electrode for measuring the electrical potential in reinforced concrete structures
Witeklab Stable Reference Electrode (W-S-RE) is a new type of corrosion reference electrode designed to measure and monitor corrosion potential in reinforced concrete structures. It was developed in collaboration with the Polytechnic University of Valencia (UPV).
Unlike other electrodes on the market, the W-S-RE does not contain toxic materials or contaminants. Its mortar-based composition also makes it less dependent on ambient temperature and electrical noise than similar equipment and ensures a much longer service life. The electrode potential of the W-S-RE does not appreciably change until the concrete carbonates. At this point, the pH will decrease, and the resulting jump in potential can be clearly and instantly detected.
Features of W-S-RE
W-S-RE has been developed to be part of the cell configuration of sensor systems (or multisensors) so that a stable measurement potential is obtained, regardless of its value, to apply a sequence of voltammetric procedures that allow monitoring the presence of corrosion triggering and accelerating agents.
Durability and low maintenance
It does not require any type of maintenance and has great durability over time.Its metal/metal oxide design with a very stable REDOX couple contributes to its longevity and stability.
Non-contaminating
Unlike other electrodes on the market, which contain polluting or toxic elements such as mercury chloride or silver chloride, the W-S-RE is primarily made of mortar and contains no toxic or polluting materials.
Potential stability
The W-S-RE is characterized by the stability of its electrical potential over time, providing accurate and consistent measurements.
Low coefficient of variation
W-S-RE has a low coefficient of variation of potential with respect to temperature (-0.746 mV/oK), guaranteeing reliable results regardless of ambient thermal variations.
Suitable for various applications
Designed to measure corrosion potentials of reinforcement in reinforced concrete. Furthermore, it is ideal to be part of sensor or multi-sensor systems, allowing the monitoring of corrosion triggering and accelerating agents.
Main applications
Measurement of corrosion potentials in reinforcement embedded in reinforced concrete, through the permanent installation of the electrodes in the structure.
Integration into structural health monitoring systems (SMH) through sensors, to monitor the presence of corrosive agents.
In combination with cathodic protection systems, W-S-RE allows the corrosion potential to be monitored and provides greater control of the effect of the protection on the structure.
In aggressive environments, incorporating W-S-RE into sensor or multi-sensor systems enables corrosion triggers and accelerators to be detected.
