Colorimeter NCC-101 is a cost effective product and is used for better test accuracy & measurement of YI yellowness or WI whiteness index. The measurement accuracy is enhanced through white & black calibration. Measurement can be done at multiple spots for average readings. This colorimeter gives ultra stable performance throughout the operations.
