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.
FEATURES
- 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.
PRINCIPAL USE
- 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.
