Uni tronic™ Network Tester
The Uni tronic™ Network Tester is small, lightweight and quick to use. It tests circuits for electrical leakage and continuity. The first function reliably indicates damaged legwires, while the second shows both short- or open-circuit conditions and is a useful diagnostic tool.
It is inherently safe because both voltage and current are limited to values too low to initiate any known electric or electronic detonator.
