Digital measuring head for illuminance V-Lambda FLAD 03 VL1

New V-lambda sensor for indoor measurements

published on Jan 29, 2019

The spectral range of the new digital radiation sensor FLAD 03 VL1 corresponds to the sensitivity of the human eye and complies with the device class B as per DIN 5032. The measurement is cos corrected.

The spectral range of the visible light is referred to as V-lambda. The measured value is a measure for the perceived brightness.

  • measuring range V-lambda 1 lx to 200 klx
  • spectral sensivity 380 nm to 720 nm
  • absolute error smaler than 5%
  • minimum resolution 0,02 lx
