型号CE-IT绝缘装置测试仪是一种全自动，高敏感的设备，用于测试埋地管道绝缘和隔离管道过路套管，以确定其有效性。CE-IT有一个液晶读数显示被测绝缘体英语的条件。听到声音信号时，CE-IT运行，脉动音测试周期完成时的速度增加。  
 

工作原理：

The actual resistance of a buried insulator depends on many factors, such as the environment in which the joint is located. In a very low resistivity environment, the normal resistance measurement for an insulating joint may be as low as 0.5 ohm. 埋地绝缘装置的真实电阻取决于许多因素，诸如绝缘装置所处的环境。在一个非常低的电阻率的环境中，一个绝缘接头的正常电阻测量值可能是低至0.5欧姆。
