This product moves up sensitivity and measuring speed compared with current model SR-UL1R.
This SR-UL2 is the measuring instrument suitable for measuring Mega-contrast FPD, whose measuring range from 0.0005 to 300,000 cd/m² and lowest measurable luminance up to 0.0005cd/m².
The measuring time is about 17sec at 0.005cd/m², which is the fastest level in the measuring instrument field.
This product can be used for not only design and development department but also quality control in the production line.
￭ Ultra-low luminance measurement.(0.0005 cd/m² or more)
￭ High sensitivity and wide dynamic range.(0.0005 – 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-UL2 and PC is accelerated with USB and STB command.
￭ Application soft CS-900A is standard accessories.
￭ A various of flat panel display, FPD related materials.
￭ Outdoor billboard, Digital signage.
￭ Automobile instrument panel, audio, lamp and operating panel.
￭ Traffic sign, Traffic light.
￭ Generic illumination, Special illumination.
