Besides the measurement of absolute values, the instrument can also display values relative to a defined standard (target). That way differences in brightness and colour on large surfaces or similar items can be quickly ascertained.
The CS-150/160 Spot Incident Colour Meter can measure the luminance and colour values for all types of light sources including signal and traffic lights, airport runway lighting, lamps, LED's, etc. The wide measurement range of 0.01 cd/m2 to 999,900 cd/m2 (CS-160 0.1 cd/m2 to 9,999,000 cd/m2) and adjustable integration time ensures that the CS-150 or CS-160 can be used for most luminance and chromaticity applications.
