Socket & See SOK60/16HD 400V Industrial Socket Tester
400V 4 Pin Industrial Socket Tester with Phase Sequence Indication
The Socket & See SOK60/16HD 400V Industrial Socket Tester is designed for quick testing of 400V 4 pin industrial socket outlets, providing clear visual and audible indication of phase presence, phase sequence and protective earth condition.
Simply connect the tester to the industrial socket and switch on the supply. The LEDs indicate whether phases L1, L2 and L3 are present, while the tester also provides immediate phase sequence indication. A correct clockwise sequence is shown by three rotating green LEDs with a continuous tone, while an incorrect counter-clockwise sequence is indicated by three rotating red LEDs with a warbling warning tone.
The fourth PC-N LED provides indication of the protective earth conductor when all three phases are present. Green indicates its presence, while red indicates its absence.
For testing 32A industrial sockets, the Socket & See SOK60 can also be used with the optional SOK ADP60 adaptor.

Why Choose the Socket & See SOK60/16HD?
The Socket & See SOK60/16HD is designed to make checking 400V industrial sockets quick and straightforward.
Its combination of colour-coded LEDs and audible tones allows the user to identify correct or incorrect phase sequence at a glance. If a phase is missing, the corresponding LED remains off while the other phase LEDs flash to show that they are present.
The additional protective earth indication provides further useful information about the socket condition, while the tough rubber holster and hard-wearing cable make the 400V 4 Pin Industrial Socket Tester well suited to regular professional use.
