Profile: Maurer Magnetic AG specializes in industrial demagnetizers, magnetic measurement instrumentation and permanent magnets. We manufacture specialized products for the precise measurement of magnetic fields on ferromagnetic parts and magnetic materials. M-Test MK4 precisely detects and measures static or dynamic magnetic fields. The tangential probe is only ~1mm thick, permitting exact, accurately positionend measurements at hard-to-reach spots or on surfaces. The M-test MK4 is especially suitable for measuring permanent magnets or small ferromagnetic parts. Magnetic fields are easily detected by the fast-reacting color LED, when the user runs the probe over the surface of the part. The peak hold function is controlled by pressing the button on the probe, which makes it possible to easily find and determine the spots with the highest field strength for any polarity.
