產(chǎn)品描述：

DCVG/CIPS 近間距管地電位/直流電壓梯度測(cè)量

特點(diǎn)：
1、全面檢測(cè)外防腐層的現(xiàn)狀，包括：防腐層老化情況、破損位置及破損大小狀況，破損處管體的腐蝕電流的流向等，評(píng)價(jià)其完整性情況；
2、全面掌握陰極保護(hù)系統(tǒng)的運(yùn)行情況，對(duì)其保護(hù)水平（管道是否獲得全面、合適的陰極保護(hù)，是否存在欠保護(hù)及過保護(hù)情況）給予測(cè)量評(píng)價(jià)；
3、掌握雜散電流分布的情況，評(píng)價(jià)其對(duì)管道外腐蝕的影響。

包括：
●測(cè)量主機(jī)；
●可測(cè)量距離的分配器；
●兩個(gè)探仗；
●電池充電器。
