Pipeline potential recorder

The utility model provides a pipeline potential recorder, belongs to the technical field of pipeline systems, and solves the problem of low measurement precision of power-on potential and power-off potential of pipeline potential. According to the technical scheme, the device is characterized in that the device comprises a data recorder and a reference electrode, an acquisition module, a correction module and a storage module are installed in the data recorder, and a first temperature sensor is installed in the reference electrode. And meanwhile, the acquisition module acquires the temperature measured by the first temperature sensor, then the power-on potential and the power-off potential are corrected through the correction module, and after the correction module processes the power-on potential and the power-off potential, the precision of the power-on potential and the power-off potential is improved. 本实用新型提出一种管道电位记录仪，属于管道系统技术领域，解决了管道电位的通电电位和断电电位测量精度低的问题。其技术方案要点是：包括数据记录仪和参比电极，数据记录仪内部安装有采集模块、修正模块和储存模块，而参比电
