B&W LumaFlux Tangential Field Strength Meter

B&W LumaFlux Tangential Field Strength Meter

Dual UV & White Light and Tangential Field Strength Meter


Powerful and Portable Combined UV / White Light and Tangential Field Strength Meter

The Baugh & Weedon LumaFlux combines all the established functions of the LumaCheck Dual UV / White Light Meter and the unique benefits of the MagnaCheck 3D Tangential Field Strength Meter in one rugged instrumentation package. With the easy "Swap & Go" system to change sensors, the LumaFlux automatically recognizes the Sensor that is connected and operates in the selected mode until the sensors are swapped again. The unique 3D sensor will increase your efficiency and save you time, while its rugged, ergonomic design ensures that no matter your application, the LumaFlux is up to the task.



  • Two instruments in one allowing you to save on purchase cost
  • Excellent result accuracy in all measurement modes
  • Lightweight, compact and housed in a rugged enclosure
  • Battery powered
  • Ergonomically designed with protective rubber boot
  • Full color programmable library
  • Programmable calibration reminder
  • Separate probes and cables for convenience and lower spares and maintenance costs

*Note: the specifications below refer to the LumaCheck and the MagnaCheck 3D, both of which combined make up the LumaFlux
