View our latest version of this instrument, the CM-3700A.
The CM-3700d spectrophotometer is a bench-top unit which provides the highest level in accuracy and reliability. It features a large sphere, aperture masks, and a complete optical system which exceeds international standard requirements. This instrument emits a high power xenon flash when a measurement takes place to ensure the most accurate measurement is taken. Users are able to switch the size of the measurement area depending on the needs of their application and can choose from 25.4mm, 8mm, and 3x5mm.
The CM-3700d easily measures reflective colors by with the ability to switch between SCI and SCE. Florescent colors can also be easily determined with the instrument s UV cut filters which allow 1,000-step adjustment of UV light, providing ideal measurement of paper, pulp, and other materials containing florescent materials. Also, diffused lighting allows transparent colors to be effectively measured. These unique features allow a wide range of applications to be measured including plastics, textiles, dyed items, kiln-fired materials, food, liquids, and others. The CM-3700d can be controlled by a PC via a USB cord. It is compatible with Windows programs, making data control and editing easy.
This instrument is compatible with SpectraMagic NX software which is easy-to-use and displays multiple views of data results which can be edited. Target data of the primary target can be associated to two or more secondary targets, allowing for sophisticated QC applications, such as checking for color difference.
A variety of graphs can be used to display information, preconfigured templates are available, and a status window is available to show instrument information at a glance. Data compiled with older software is compatible and can be transferred to the newest updated software. If Excel is needed to show data, the information can also be easily exported. A Navigation Function and Color Tutorial are included with the software for additional information.
