Outline

The previous model SR-UL1 made it possible to measure very low luminance as low as 0.005cd/m².
This product inherits high quality from the SR-UL1 and its operability is enhanced with USB interface and motorized aperture angle.
Latest grade up make SR-UL1R to extend guaranteed accuracy range to 0.001 cd/m²

Features

Features

  • Ultra-low luminance measurement. (0.001 cd/m² - )
  • High sensitivity and wide dynamic range (0.001 - 300,000cd/m²)
  • Luminance and chromaticity in small area can be measured without attachment lens.
  • The stable measured value are obtained even when measuring frequency light source.
  • Communication between the SR-UL1R and PC is accelerated with USB and STB command.
  • Application soft CS-900A is standard accessories.
     

Applications

  • a various of flat panel display、FPD related materials
  • Outdoor billboard、Digital signage
  • automobile instrument panel、audio、lamp、operating panel
  • Traffic sign, Traffic light
  • Generic illumination, Special illumination
