发布时间:2023-02-27

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。
