昆山英国CROPICO DO4002毫欧表CROPICO-山东搜宝电子有限公司

产品介绍：

英国CROPICO DO4000系列便携式数字毫欧计

产品型号有：DO4000/DO4001/DO4002
功能与特点：

* DO4000系列是一款的手持式数字毫欧表

*采用四线法（Kelvin开尔文原理）测量低电阻，避免了导线产生的测量误差

*测量量程从10μΩ到4000Ω的电阻，4002型小达1μΩ

* 4位液晶数字显示

*手动和自动量程选择

*如果出现错误连接或测量错误，仪器能提示错误信息。

*如果出现外部电压的危险状况，仪器也会自动提示

*坚固的ABS塑料外壳设计，抗摔打

*正反向测量，平均值自动计算

*自动校零功能

*因导线受温度影响较大，如需更的测量，请选用4001型，独有温度补偿和温度测量功能。
