Problems solved by technology
The former is complex to install and difficult to maintain, and the failure of the reference electrode often leads to deviations in measurement results during use, resulting in wrong evaluation of the degree of cathodic protection
When the latter is measuring deep-sea structures, the cables are often confused due to the long measurement distance, and at least two people are required to operate during the measurement process: one person uses a multimeter to measure, and the other person performs cable retraction, which increases the difficulty of the operator's work and affects Operational Measured Efficiency

The invention has the advantages of simple structure and convenient use, and is suitable for the potential measurement of metal structures in the deep sea environment.
Description
Technical field [0001] The invention belongs to the technical field of marine anti-corrosion engineering, and particularly relates to a portable electric potential detection device and a use method thereof. Background technique [0002] Marine metal structures such as offshore platforms, submarine pipelines, ports, and tidal power stations need to take cathodic protection measures to prevent corrosion damage in harsh marine corrosive environments, and cathodic protection potential is an important parameter to measure the degree of protection of protected objects. The detection of cathodic protection potential generally adopts two methods. One is to use a reference electrode fixed on the structure and a monitoring device on the platform to detect the protection potential; the other is to use a portable reference electrode and a multimeter to detect the protection potential. The former is complicated to install and difficult to maintain. In addition, the failure of the reference e...
