EX3 colorimeter

The EIZO EX3 colorimeter automates and simplifies monitor calibration in connection with EIZO ColorNavigator. The colour sensor is connected to the EIZO ColorEdge monitor via USB interface. The calibration targets are set within ColorNavigator. The hardware calibration then takes place automatically. The sensor measures a number of colors on the screen and ColorNavigator finally creates a "profile", which is used by the colour management of the operating system as a reference for the monitor.
