Intrinsically-Safe Continuity Tester
The EX-DT12 Intrinsically-Safe continuity tester is a handy and robust testing device for use in potentially explosive areas. The electronics are housed in the test probe, which means the basic device does not have to be handled during measuring and leaves both hands free for the test operation.
The combination of optical and acoustic readout permits usage in a loud environment.
