        机动数字式接地电阻测试仪DEL2/2

        ·计算机控制,具有先进手段滤波功能。
        ·异常之移频设计。
        ·准确
        ·清晰、强烈的告诫及错误提示。
        仪器说明:
                 DET2/2是一种电动数字式接地电阻测试仪,具有微处理器控制,具有先进的滤波功能。10mΩ~20kΩ量程自动转换,可三头、四端测试。可测简单、复杂、大型的接地网的接地电阻(如发电厂,火车站,血站,电脑和通信系统,电磁干扰(EMI)射频干扰(RFI)系统,适用天线电视(CATV)系统之接地,以及天线,地方控制系统和系统底座的接地等),并可测土壤电阻率。
        3位半LCD大屏幕显示。
                 DET2/2异常之移频设计。她测试频率可在100-160HZ之间以0.5HZ�i行,可有效避开测试现场强烈干扰源干扰频率的影响,配合滤波处理使仪器能在肯定干扰场所正常测试。干扰抑制达40V。
        准确:±0.5% :±2位(23℃)
                DET2/2借鉴简便,面试迅速。充电电池一次充电可持续工作5个小时。
                DET2/2能够测试大的接地系统。面试范围宽、精度高、抗干扰能力强。
