Description

Technical Field

[0001] The utility model relates to the technical field of electrodes, in particular to a cathode protection potential on-site testing device. Background Art

[0002] The copper sulfate reference electrode is part of the cathodic protection system. The durability, endurance, and damage resistance of the buried long-lasting copper sulfate reference electrode (especially when used as a control signal source for impressed current cathodic protection) have always been one of the important components that attracts more attention in engineering construction. The cathodic protection potential field test device is a device used to measure the potential in the cathodic protection system of metal structures. It is used to evaluate whether the metal structure is adequately cathodically protected to prevent corrosion. The test device helps engineers monitor the performance of the cathodic protection system and ensure that the metal structure is properly protected.

[0003] Typically, underground pipelines need to be tested regularly using a cathodic protection potential field test device to ensure that the pipeline system is effectively protected against corrosion. These tests can help monitor potential changes on the pipeline surface, ensure the normal operation of the cathodic protection system, prevent pipeline corrosion, and extend the service life of the pipeline. Underground pipelines are located deep and the operating space inside or near the pipeline is limited, which makes it impossible for workers to maintain the stability of the copper sulfate reference electrode during manual testing, affecting the quality of the test.
