ColorReaderPRO, ColorReader and ColorReaderEZ measure and suggest the closest match to popular paint fan decks. However, they have several key differences.
ColorReaderPRO has an OLED display, this allows it to operate independent of the ColorReader app (iOS and Android) where ColorReader and ColorReaderEZ need the app in order to function. The ColorReaderPRO is larger and includes a pouch for storage while on the job site. All ColorReaders need periodic calibration; the calibration tile is integrated into the cap that protects the sensor on the ColorReader and the calibration tile is stored in the pouch of the ColorReaderPRO.
