CorroWatch Multisensor

Features & Benefits

• Early warning at multiple depths – monitors corrosion activity at different depths within the concrete cover.
• Designed for new construction – embedded during construction, with adjustable anode heights to suit the concrete cover thickness.
• Supports proactive maintenance planning – provides condition information before corrosion-related deterioration becomes visible.
• Flexible monitoring options – readings can be taken using the CorroZoa handheld meter or through a compatible datalogger.
• Suitable for difficult-to-access locations – provides embedded monitoring where future visual inspection may be difficult.

Applications

CorroWatch is intended for new concrete structures where early detection of corrosion initiation and long-term monitoring are important.

Typical applications include:

• Tunnels and bridges in marine environments
• Bridge decks and other structures exposed to de-icing salts
• Parking structures
• Structures exposed to aggressive environmental conditions
• Locations where future inspection access is limited

How It Works

CorroWatch uses four black steel measuring electrodes positioned at different depths within the concrete cover. As the conditions that initiate reinforcement corrosion progress through the concrete cover, each electrode provides an indication when corrosion activity reaches its depth.

The resulting change in current between each anode and the cathode is measured using the CorroZoa meter or a compatible datalogger. Because measurements are taken at several depths, CorroWatch provides staged early warning as corrosion conditions progress toward the reinforcement.
