Robin has developed its own professional range of socket testers with modern, ergonomic and durable designs.
Robin has developed its own professional range of socket testers with modern, ergonomic and durable designs.
The range consists of three units - the SM100, SM200 and SM300 - with varying features and functions to suit the application.
The top-of-the-range Robin SM300 SocketMaster is a professional test tool designed for electrical contractors to test the safety of installed mains sockets.
It is the only socket tester on the market which also checks 30mA RCDs.
A unique soft-touch button tests that an RCD in the circuit trips within 300ms when a nominal 30mA earth fault current is applied.
A further button, the earth volts touchpad, detects raised earth voltages above 50V AC, thus indicating potentially dangerous installations.
Three vivid bicolour LEDs and a buzzer on the SM300 provide a quick-to-check combination of signals which indicate correct wiring, missing earth, live/neutral reverse, earth/live reverse, missing neutral, live faults, and those errors detected by the two pushbutton tests.
In the event of a detectable fault occurring, the buzzer will pulse, instead of issuing a continuous tone.
The SM200 and the SM100 offer the same five checks of wiring connections, without the soft-touch button tests.
The SM200 has a similar audible warning feature to the SM300 to aid detection of wiring faults.
