The Gardner Bender GK3 is a tester kit. This kit includes voltage, continuity and receptacle testers. The voltage tester tests polarity and voltage in outlets. With the help of a continuity tester you can indicate the continuity on wires, fuses and light bulbs. Also, if you need to detect wiring condition, you can use the receptacle tester.
