Product introduction
It is composed of copper -- copper sulfate reference electrode and carbon steel plate and salt bridge around it. The steel plate is connected with the pipeline under test through wire and test pile and introduced polarization. It can effectively eliminate potential error caused by soil IR drop, stray current and other factors, so as to achieve accurate detection of the protection potential value on the protected structure.
The main parameters
Probe internal resistance: 200 ω ~ 1.6 K ω Operating temperature: -20 ~ 40℃ Probe material: engineering plastic Shape size: φ110×185mm test line length: 5 meters
Method of use
1. After the completion of the test, clean the polarization probe, tidy up the test cable, and re-stick the sealing film at the bottom. At this time, the potential value displayed on the screen of the potential tester is the actual potential value of the structure under test.
2. Connect the yellow test cable in the polarization probe test cable and the structure under test, and connect the positive end of the electric potential tester to the red test line and the negative end to the black test line.
3. If it is used for long-term potential detection of protected structures, it needs to be buried deep below the frozen soil layer. The polarization probe is manufactured using advanced technology. . Thus, the resistance voltage drop of the measuring channel is reduced to the minimum and the interference of external current is effectively shielded. The measurement of pipe ground potential which is very difficult in the stray interference area becomes simple, smooth, reliable and true. Compared with similar foreign products, it has the advantages of novel structure, good non-disturbance, solid and reliable, long service life, easy to carry and in the engineering field application, etc., and the CSE (copper/copper sulfate reference electrode) commonly used in soil cathodic protection engineering in China to measure and mark the reference potential (entrance polarization probe commonly used SCE), Therefore, it is a new generation of reference electrode more suitable for China's national conditions. Polarization of the probe
4, first of all, remove the sealing film at the bottom of the polarization probe, and soak in water for more than 12 hours.
5. Then place it in a pre-designed test position.
