Field Strength Meter

VFM2 – for measuring the magnetic field strength / flux density of DC and alternating fields

• Description

  The VFM2 field strength meter VFM2 is ideal for use in industry and production to measure the static magnetic field strength / flux density on surfaces of ferromagnetic parts. For the reliable localization of the so-called "residual magnetism", an alarm limit value can be set individually for each of the five switchable measuring units and if reached indicated acoustically and visually. In combination with the automatic peak memory function, larger surface areas can be checked safely and quickly.

  The integrated Bluetooth® data interface and the optionally available evaluation software VFM2 STATISTICS enable single and series measurements and simplify the statistical evaluation of measured values. Alternatively, the measured values can also be transmitted directly to a customer's quality data acquisition system.
