The new installation testers included in the PROFITEST MF series are ideally matched to the electrician’s requirements and are specially designed for the implementation of electrical tests in installations and systems – day in, day out.

The MF series represents the consistent further development of the well-established PROFITEST series with its unique operating concept. The intuitive rotary switch for quick selection of measuring and control functions, as well as the high-resolution, context-sensitive color graphic display – in conjunction with automatic test sequences – provide the user with practical operating convenience.

Thanks to highly diverse application options with various accessories and adapters, users are also well prepared for future challenges. New measuring functions and test sequences can be imported by means of a simple firmware update –our service guarantee for you, so that you’ll still be up to date even 10 years down the road!
