KONICA MINOLTA LS-150/160 skaisčio matuokliai

  • LS-150 ir LS-160 yra lengvi, kompaktiški skaisčio matuokliai skirti įvairioms skaistumo sąlygoms matuoti. Skirtingai nuo LS-100 ir LS-110, naujos kartos instrumentai siūlo patobulintas funkcijas ir patogumą. Šios priemonės užtikrina didesnį matavimo diapazoną ir pagerintą V (λ) koreliaciją.

     

    Pagrindinės pritaikymo sritys:

    • CRT, LED, ir EL skaisčio matavimas
    • Kelių ir tunelių apšvietimo ryškumo matavimas
    • geležinkelio signalų matavimas
    • kelių ir oro uosto signalų matavimas
    • lauko apšvietimo ir ženklų matavimas
    • apšvietimo įrangos ir prietaisų matavimas
    • mokslinių tyrimų ir bandymų matavimas
    • įrenginių šviesumo matavimas
