型號CE-IT絕緣裝置測試儀是一種全自動，高敏感的設(shè)備，用于測試埋地管道絕緣和隔離管道過路套管，以確定其有效性。CE-IT有一個液晶讀數(shù)顯示被測絕緣體英語的條件。聽到聲音信號時，CE-IT運行，脈動音測試周期完成時的速度增加。  
 

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. 埋地絕緣裝置的真實電阻取決于許多因素，諸如絕緣裝置所處的環(huán)境。在一個非常低的電阻率的環(huán)境中，一個絕緣接頭的正常電阻測量值可能是低至0.5歐姆。

Checking the insulating joint of a buried pipeline for current leakage is often a more reliable test than an internal resistance test. 通過檢測埋地管道絕緣裝置的漏電情況要比直接測量內(nèi)部電阻要更為可靠。  漏電流的絕緣接頭比內(nèi)部電阻的測試通常是一個更可靠的測試。
