The Color Viewing Box is a simulation instrument which is mainly used in quality control. The Color Viewing Box accurately simulates illuminants and thus enables the direct comparison of products which must have special colour characteristics. The Color Viewing Box PCE-CIC 10-LED supports six possible illuminants. These illuminants are included as standard: "A/F", "D65", "TL84/F11", "UV", "CWF" and "TL83/U30".

Metamerism can thus be avoided by using a Color Viewing Box. As a support during the measurement, the Color Viewing Box has an hour counter which makes it easier for the user to adhere to the recommended operating time of the lamps. The illuminant is selected by the user independently by the touch of a key. In addition to the individual light, it is also possible to switch to mixed light by pressing the required keys at the same time.
