Martindale PC105 63A 3-Phase Socket Tester

A quick and easy-to-use three-phase socket tester, the Martindale PC105 is made to examine the wiring quality of five-pin 63A sockets. The 3-phase socket tester only needs to be plugged into the intended outlet for it to start automatically assessing the socket. The PC105 provides an LED indicator of both the proper and faulty/missing phases by checking for phase, phase sequence, PE, and neutral presence.
