Tinker & Rasor CE-IT - Below Ground Insulator Tester

The Model CE-IT Insulator Tester is a fully automatic, highly sensitive electronic instrument designed to test the effectiveness of buried pipeline insulators. The CE-IT can also be used to determine the isolation condition of pipelines in road crossing casings.

The Model CE-IT circuit automatically adjusts to the voltage polarity present on the underground piping system under test. A readout of the test results is displayed in English on the LCD meter.

• GOOD: This is displayed when the Model CE-IT determines that the electrical load placed on the pipe on either side of the isolator is not leaking from one side to the other, so it is able to build a capacitive load, and therefore determines that the isolator is effective.
• BAD INPUT SHORT: This is displayed when the Model CE-IT determines that the electrical load placed on the pipe on either side of the isolator is leaking from one side to the other, so it is not able to build a capacitive load, and therefore determines that the isolator is not effective.
• BAD INPUT OPEN: This is displayed if the Model CE-IT is not able to electrically load one or both sides of the isolator. This result indicated a broken lead wire to one or both sides of the isolator on the pipe system under test.

The entire testing procedure is complete in less than 30 seconds, an audible signal alerts the operator when the test cycle is completed. Although the Model CE-IT is equipped with power start switch, the instrument will automatically shut off in 10 minutes if not in use, to conserve batteries.

The Model CE-IT is factory calibrated, ready to use and requires no field adjustment.
