Using corrosion coupon racks is a well-established, low-cost method of measuring corrosion rates, but they only provide retrospective data after exposure. By adding online corrosion monitoring to complement coupon racks, you gain several additional benefits:
## Real-Time Insight
- Coupons need weeks or months of exposure before results are available.
- Online probes employing Linear Polarization Resistance (LPR) provide continuous, near-real-time corrosion data, allowing you to quickly determine the impact of dosing adjustments, temperature swings, or changes in water chemistry.
You can learn more about CWC’s systems for this under [corrosion monitoring solutions](https://cwc.com.au/products/cooling-tower-boilers/corrosion-monitoring/emec-ecorr-corrosion-rate-sensor-for-steel-copper-304ss-and-other-metals/).
## Improved Chemical Dosing Control
- Online monitoring shows how corrosion responds immediately to inhibitor feed rates, pH control, or biocide additions.
- This enables optimization of treatment programs — reducing overdosing (cost savings) and preventing underdosing (asset protection).
For support implementing optimised programs, you can [speak with a specialist](https://cwc.com.au/contact/).
## Event Detection and Early Warning
- Coupons cannot capture transient corrosion spikes from upsets like oxygen ingress, system leaks, or loss of treatment feed.
- Online monitoring can detect these excursions in real time, allowing corrective action before significant metal loss occurs.
Explore these capabilities in CWC’s [LPR corrosion monitoring systems](https://cwc.com.au/products/cooling-tower-boilers/corrosion-monitoring/emec-ecorr-corrosion-rate-sensor-for-steel-copper-304ss-and-other-metals/).
## Better Data Resolution Coupons give an average corrosion rate over the exposure period. Online probes capture dynamic changes and can distinguish between stable baseline conditions and sudden corrosion events. This richer dataset supports root-cause analysis and predictive maintenance. For more detailed system options, [visit corrosion rate sensors](https://cwc.com.au/products/cooling-tower-boilers/corrosion-monitoring/emec-ecorr-corrosion-rate-sensor-for-steel-copper-304ss-and-other-metals/).
## Operational Efficiency
Reduces the need for frequent site visits and manual coupon retrieval.
Supports remote monitoring and integration with plant control systems (SCADA/DCS).
Improves decision-making and reduces downtime.
If you'd like to discuss integrating these technologies, feel free to [get in touch with our team](https://cwc.com.au/contact/).
## Best Practice
Use both systems in combination. Coupons remain valuable for physical verification of corrosion type, while online monitoring provides fast, actionable intelligence. Together they give the most complete picture.
