Socket & See SOK40/16HD 230V Industrial Socket Tester
230V 3 Pin Industrial Socket Tester with Wiring Fault Indication
The Socket & See SOK40/16HD 230V Industrial Socket Tester provides a quick and straightforward way to check 230V 3-pin industrial socket outlets for correct operation and common wiring faults.
Simply insert the tester into the socket and switch on the supply. The SOK40/16HD first performs an automatic self-check, shown by the LEDs flashing red and green. Once the self-check is complete, the LEDs and audible buzzer indicate whether the socket condition is correct or whether a fault has been detected.
A continuous audible tone indicates a correct condition, while a strong warbling tone warns of an incorrect or faulty condition. The indication guide on the front of the tester can then be used to identify the fault condition.
The Socket and See SOK40/16HD can indicate conditions including L-E reverse, L-N reverse, faulty neutral, earth or live, and missing live, making it a practical industrial socket tester for electricians carrying out routine checks on 230V installations.
For electricians who commonly refer to these connections as Commando sockets, the SOK40/16HD also provides a practical Commando socket tester solution for compatible 230V 3-pin industrial outlets.
For testing 32A industrial sockets, the Socket & See SOK40 can be used with the optional SOK ADP40 adaptor.
