By Type, the corrosion monitoring market is segmented into electrical resistance (ER) probes, linear polarization resistance (LPR) probes, ultrasonic thickness gauges, and chemical sensors. The electrical resistance (ER) probes segment held a significant share of the market in 2025. ER probes are widely used in oil & gas pipelines, chemical plants, and water treatment facilities due to their ability to provide continuous and accurate monitoring of metal loss caused by corrosion. Their cost-effectiveness and compatibility with various metals drive adoption in this type segment globally.
By Technique, the market is segmented into offline (manual inspection) and online (real-time monitoring) techniques. The online monitoring segment held the largest share of the market in 2025. Online techniques are preferred in critical infrastructure such as pipelines, storage tanks, and industrial machinery due to their ability to provide continuous, real-time data on corrosion rates, enabling predictive maintenance and reducing the risk of unexpected failures. The increasing need for operational efficiency and safety fuels growth in this technique segment.
By Application, the market is segmented into oil & gas, power generation, marine, chemical processing, and water & wastewater treatment. The oil & gas segment held the largest share of the market in 2025. Corrosion monitoring in this sector is critical to preventing leaks, equipment failures, and environmental hazards. The extensive use of pipelines, offshore rigs, and refineries, combined with stringent safety and environmental regulations, drives demand for advanced corrosion monitoring solutions in the oil & gas industry globally.
By End User / Industry, the market is segmented into industrial manufacturing, energy & utilities, oil & gas, marine & shipping, and chemical processing. The industrial manufacturing segment held the largest share of the market in 2025. Corrosion monitoring is extensively implemented in industrial plants to protect machinery, reduce maintenance costs, and ensure uninterrupted production. The growing focus on predictive maintenance and asset reliability across manufacturing sectors is a key factor driving growth in this industry segment.
By Vertical / End User, the market is segmented into residential, municipal, industrial, and commercial. The municipal segment held the largest share of the market in 2025. Municipal authorities rely on crawler camera systems to inspect drainage networks, sewer lines, and stormwater systems to ensure uninterrupted service and compliance with environmental standards. The increasing focus on urban infrastructure management and public safety fuels growth in this segment.
