The standard Ultra-Violet (UV) filter in this instrument, used to set UV Nominal, Calibrated, Excluded and Custom settings, is a 400-nm UV cut-off filter. This kit adds an additional 420-nm UV Cut-off filter for IN (UV-excluded) and OUT operation.
The kit includes the 420-nm UV cut-off filter and installation documentation. This CMR can be installed by Hunter Lab at the factory or in the field by a Hunter Lab distributor or a knowledgeable customer. If the EasyMatch QC version number (HELP > ABOUT) is less than 4.20 or CMR-2900 UltraScan PRO OCX is less than version 1.10, a software upgrade to the current released version (purchased separately) will be required to allow the software to recognize this 420-nm UV Filter option.
