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.

Application Examples

The DENKweit technology is used across a variety of different applications.

Shingled Modules (photovoltaics)

  • Measurement of the distribution of currents in connected Shingled Solar modules
  • Analysis of the quality of individual adhesive points by simply stroking the detector over
  • Quick detection of hidden shunts and other inhomogeneities
  • Optimization of series resistors and Shingle concepts
  • Use in production and free field


Cell Connectors (photovoltaics)

  • Measurement of a solar cell
  • The right busbar is not connected to the cross connector


Batteries (cylindrical cells)

  • Measurement of three cylindrical Li-Ion batteries during a charging process
  • The right battery shows an abnormality
  • The changed magnetic field indicates a locally changed current flow
  • MFI allows the detection of defects in accumulators


Batteries (pouch cell)

  • Measurement of a pouch cell during the charging process
  • MFI makes it possible for the first time to visualise the flow of electricity

Cracks (metal processing)

  • Measuring a crack in the metal with a handheld device
  • Measuring signal 3-4 orders of magnitude via signal-to-noise ratio
  • Live measurements possible
