ELECTRIC SOCKET TESTER EARTH & 30 mA RCD TESTS

With its compact format, the MX 531 can be used one-handed and its wrist strap makes it easy to transport.

Itsrotary head makes it easy to use wherever the 2P+E socket is located and the backlit display ensures that it is easy to read. The measurement result remains displayed for 10 s.
The backlighting has a second function as it changes colour:
‐ blue when the MX 531 is connected to the socket
‐ red if the measurement does not comply,
‐ grey if all the results comply and the MX 531 is disconnected

The MX 531 is an electrical socket tester which can be plugged into all socket configurations:

  • it checks that an electrical socket in a TT system is operating correctly
  • it measures the voltage and displays the conductor connections on a single-phase 2P +E socket
  • it automatically measures the earth resistance RE
  • it performs a trip test on the 30 mA RCD

In addition, depending on the results, pictograms are displayed to provide further confirmation concerning their conformity. This stand-alone instrument without batteries is recharged directly on the mains. Self-employed electricians and installers, maintenance technicians: the MX 531 is designed to simplify your job every day.
It is delivered with a wrist strap and a carrying bag.
