The FT3424 is a light meter designed for an extensive range of applications involving illumination equipment, lighting work and facility management. Capable of testing even LED lighting, the FT3424 provides five measurement ranges, 20 lx to 200,000 lx, to support a wide range of luminance levels.
Relative Spectral Response Characteristics in the Visible Spectrum
Human perception of brightness ranges from 380 nm to 780 nm in the wavelength and is the maximum at 555 nm. The lnternational Commission on Illumination (CIE) has established comparative standards for luminosity, setting the maximum perception for 1 and indicating the amount of perception of each wavelength by the relative value, and calculating the average of many people. In this instrument, the relative spectral response characteristics are close to the comparative standards for luminosity.
