Terminator Electrical Tester TNT 153S
Terminator Neon Tester is a pocket-sized tool having two probes and mainly works better on AC voltage. It uses a neon indicator to test the circuit. Initially, the indicator does not have a light of its own, but it glows when it detects the power in the circuit. Apart from checking the voltage, it checks whether the circuit is properly grounded or not. If the outlet is grounded correctly, the light won’t glow in the circuit.
