LGR1000 大地网接地电阻测试仪

产品概述                                                                                   

LGR1000 大地网接地电阻测试仪适用于测试各类接地装置的工频接地阻抗、接触电压、跨步电压、转移单位、场区地表电位梯度等工频特性参数以及土壤电阻率。

性能特点

1.采用异频交流电源输出，抗干扰能力强；交流电流输出仅需3A，故仪器本体重量轻，体积小；

2.降低了对测试线径的要求（仅需1.5mm2），有效地降低了劳动强度；测量结果直接显

示，勿需另外计算；                                                                              

3.大屏幕液晶显示，全中文傻瓜式菜单操作，操作直观、简单、方便。
