鉗形接地電阻儀

ETCR2000 鉗(qian)形(xing)接(jie)(jie)(jie)地電(dian)(dian)(dian)阻(zu)儀用于電(dian)(dian)(dian)力(li)、電(dian)(dian)(dian)信、氣象以及其(qi)它電(dian)(dian)(dian)氣設備的接(jie)(jie)(jie)地電(dian)(dian)(dian)阻(zu)測量。 　　ETCR2000 有長鉗(qian)口(kou)及圓鉗(qian)口(kou)之分，長鉗(qian)口(kou)特別適用于扁鋼接(jie)(jie)(jie)地線的場(chang)合。 　　傳統(tong)的接(jie)(jie)(jie)地電(dian)(dian)(dian)阻(zu)測量方法是采用電(dian)(dian)(dian)壓(ya)——電(dian)(dian)(dian)流法。
