Socket & See 4-pin industrial socket tester for 400V systems. Instant phase sequence, clear LED indication, tough rubber case.
The Socket & See SOK60/16HD 400V Industrial Socket Tester is a robust, 4-pin tester designed for professional electricians and maintenance engineers. Housed in a hard-wearing rubber case, it delivers instant phase sequence and clearly identifies each phase as L1, L2, or L3, making it an essential tool for verifying three-phase industrial socket outlets.
Featuring an intuitive rotating LED display, the tester provides immediate, easy-to-interpret results. When all three phases are correctly connected, the green LEDs rotate clockwise and a continuous tone sounds. If the phase sequence is incorrect, the red LEDs rotate counter clockwise, accompanied by a warbling tone. A missing phase is flagged by the corresponding LED remaining unlit while the other two flash, and the protective earth (PE) status is shown via a fourth LED (green for present, red for absent).
Key Features
When used with the optional ADP60 adapter, the SOK60 can also test 32A industrial sockets, expanding its versatility on site. The secure push-fit connection ensures ease of use, while the protective case and durable build make it a reliable companion for demanding environments.
