Like with any piece of equipment or machinery, color measurement instruments need maintenance to assure that they continue to work correctly and with a predictably high degree of accuracy.

Calibration allows us to set a baseline for the instrument and make sure that the baseline is maintained over time. Daily calibration of instruments and also annual calibrations are recommended. This is the only way to maintain consistent and reliable readings.

Our procedure for daily calibration begins by taking two measurements. The black measurement, which is referred to as zero calibration, is performed by using a special attachment for the instrument that absorbs all light. The attachment is referred to as a zero calibration box.
