Digital LuxMeter 51021

The 510 series lux meter measures the intensity of illumination more accurately because its sensitivity approximates to the standard spectral luminous efficiency which is the same sensitivity as the human eye. However, since spectral characteristics differ depending on the light source types, a subtle indication error occurs. The 51021 lux meter incorporates a function to correct this error. (Factor fixed: 8 types; arbitrary factor setting: 21 types).
