A handheld digital color luminance meter for measuring the chromaticity of light sources and objects remotely without contact. Controllable from a PC via USB. This compact and battery-driven meter can be easily used at any location. Even chromaticity of difficult-to-touch objects such as freshly painted products can be measured. The difference between the target object and standard colors can be measured/displayed, allowing easy chromaticity control. Integration with the included color management software enables measuring remotely, managing data list and exporting data.
