ChromaPure Professional and Klein K10a Colorimeter
The backbone of any video measurement or calibration effort is the colorimeter. Spectroradiometers, despite their reference accuracy, do not offer either the speed or the low-light sensitivity for the front line measurement instrument. For this you need a colorimeter. The Klien K-10a is the industry standard for professional-quality colorimeters. Its speed and low-light sensitivity is the best in the business. For maximum accuracy it should be paired with a reference spectroradiometer, such as those offered by JETI or Research Colorimetry. For more information about the K-10a, read our review.
Summary
The K-10a colorimeter is unequalled for speed and low-light sensitivity.
