DENKweit B-LAB Magnetic Field Imaging

The DENKweit B-LAB is a desktop tool for measuring the direction and strength of electrical currents. It is easy to use, fast, non- contact and does not require the user to apply an electrical current during measurement. Data is highly precise, quantitative and in real time so hand held and in-situ options are also available.

The B-LAB can be combined with the DENKweit AI software DENKnetze to automatically identify faults and features. DENKnetze is affordable and easy to use.

DENKweit from Halle Germany are an award winning 2018 spin out from the Fraunhofer Institute. Their innovative Magnetic Field Imaging technology combined with their own AI solution DENKnetze has already been sold to a number of world renowned companies and institutes across a variety of applications.
