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
- Ultra-low luminance measurement.(0.001 cd/m² or more )
- 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 included as standard accessories.
PRINCIPAL USE
- 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.
