High-Chromaticity Meter

U.S.-based sales, and delivery available. The SR-5S spectroradiometer is a high-accuracy standard model designed for precise luminance and chromaticity measurement from 0.001 cd/m². Featuring improved sensitivity, high-speed measurement mode, and chromaticity accuracy of x: ±0.0015, y: ±0.001, it supports evaluation of FPD displays, automotive panels, traffic signals, and general lighting in both laboratory and production environments.

￭ Reduction of measuement speed. It can measure more speedy using High speed mode. ￭ Custom configuration supporting chromaticity accuracy of x: ±0.0015, y: ±0.001 ￭ Capable of measurements from as low as 0.001 cd/m² ￭ Reduction of measuement speed. It can measure more speedy using High speed mode. ￭ Significant improvement in usability by adopting a color touch panel. ￭ Pursuit of the best function and compatibility for measurement system installation.
