CHAUVIN ARNOUX MX531 Electric Socket Tester, RCD, 100 V to 400 V, 50 Hz to 60 Hz, 3 ohm to 1.999 kohm

MX531 is an electrical socket tester with its compact format, it 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 10s. 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 30mA RCD.
