The Model CE-IT Insulator Tester is a fully automatic, highly sensitive, LCD readout device to test buried pipeline insulators and isolation of pipelines in road crossing casings to determine their effectiveness. It automatically adjusts to the voltage polarity present on underground pipeline systems in under 20 seconds. An audible signal is heard when the test cycle is completed. Equipped with a power switch, the unit automatically shuts off in 10 minutes to conserve batteries. It comes complete with six (6) "AA" batteries and two (2) needlepoint probes.
