The SpectraCal C6 Colorimeter is one of the most advanced light measurement devices available, rivaling high-end spectroradiometers in speed and accuracy. The C6 colorimeter is field-upgradeable with CalMAN 5, meaning that the calibration tables and supported display technologies are automatically updated when the device connects with the software. Every C6 colorimeter sold is first calibrated in SpectraCal's calibration lab with a Konica Minolta CS-2000 and shipped with a NIST (National Institute of Standards and Technology) certificate of accuracy.
