The SpectroCheck is a color reference for checking the measurement accuracy of  SpectroDens, SpectroJet, and SpectroDrive. The color data of four colored ceramic samples on a turn-wheel are referenced to the NIST: National Institute of Standards and Technology, with the digital color data stored on an integrated USB flash memory.

Checking the color accuracy of SpectroDens is done by using SpectroDens Connect version 2.3 (or higher). Checking the color accuracy of SpectroDrive is done by using TECHKON ExPresso 3.2 (or higher). Both Windows software programs may be accessed from the integrated USB flash memory inside the SpectroCheck color reference, or downloaded free of charge from: http://www.techkon.de/english/code/service/

SpectroCheck leads the user step-by-step through the checking procedure, and displays a report (which may be printed out) indicating if the measurement device conforms to the technical specifications.
