MAVOPROBE MONITOR for surface-mounted measurement is classified in Class B according to DIN 5032-7, DIN EN 13032-1 Annex B and ISO/CIE 19476. It measures the brightness effect of a luminous surface in candela per square metre (cd/m²) or foot-lambert (fL). The excellent adaptation to the spectral brightness perception of the human eye V(?) with the low deviation of f1' < 3 % is significantly better than the requirement from the standard.
