Below Ground Insulator Tester


Below Ground Insulator Tester

Model CE-IT

Tinker & Rasor’s’ CE-IT is an ideal instrument for the fast and accurate testing, of below ground insulators and road crossing casings. This fully automatic unit tests the insulator without any adjustment by the operator.

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

The Model CE-IT circuit automatically adjust to the voltage polarity present on the underground piping system under test. A read out of the test results are displayed in English on the LCD meter. The entire testing procedure is complete in less than 30 second and audible signal alerts the operator when test cycle is completed. Although the Model CE-IT is equipped with power start switch, to conserve batteries the instrument will automatically shut off in 10 minutes if not in use.
