Question: 1 / 400

Which type of probe can measure corrosion in gas systems?

Galvanic probe meters

Linear polarization meters

Hydrogen probes

Electrical resistance probes

In gas systems, electrical resistance probes are specifically designed to measure corrosion by detecting changes in the electrical resistance of a material. As corrosion occurs, the cross-sectional area and thickness of the metal decrease, which leads to an increase in resistance. By monitoring these changes over time, electrical resistance probes provide quantitative data regarding the rate of corrosion, allowing for proactive maintenance and management of the system to prevent failures.

Galvanic probe meters and linear polarization meters are typically used for different methods of corrosion measurement and may not be as effective in gas environments. Hydrogen probes are used to measure hydrogen presence or activity, often in contexts that do not directly measure corrosion in gas systems. Therefore, electrical resistance probes are the most appropriate choice for monitoring corrosion within these specific environments.
