KONICA MINOLTA LUMINANCE METER LS-160

Portable, Compact, Lightweight, Ergonomic And Powered With 2 x AA batteries.

Konica Minolta luminance meter LS-160 is a successor to LS-110 and is design with highly accurate and easy-to-use luminance meter with a minimum measuring area of 4.5 mm and with greatly improved luminance range of up to 9,999,000 cd/m2. Luminance meter LS-160 uses a newly designed sensor with a spectral response that more closely match the V(λ) spectral luminous efficiency function of the human eye to provide measurement results that correlate well with visual evaluation.

The LS-160 uses a SLR (single lens reflex) optical system that provides users with several important capabilities. Very small areas, even down to 0.4 mm in diamete r(when closed-up lens is used) can be measured accurately. Measurement areas at distances both long and short show up consistently in the viewfinder. This flexibility allows even those who have never used the instrument to gather precise measurement results.

LS-160 is build on the key design features of their predecessors with new features, improved accuracy and increased measurement range.
