Voltage detection is the most basic safety test. The MD 126 offers a non-contact detection using coloured LED lights as indication. In a three phase system, the coloured lights indicate the phase sequence. A practical flashlight completes the functionality. The housing is small and light with the IP67 protection against water and dust, and 3 m drop test for robustness.
