View our latest version of this instrument, the CM-5.

The CM-3500d bench-top spectrophotometer is a multi-function unit with the ability to measure color in various applications, including reflectance and transmittance. Three measuring aperture sizes, 3mm, 8mm, and 30mm; can be interchanged depending upon the application. The transmission chamber is convenient for measuring transparent liquids or solids and the top-port is ideal for measuring the reflectance of solids, granular, powders, pastes, and opaque liquids. Users have the option to switch between SCI and SCE.

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.

Features

Highly Accurate – d/8 degrees geometry makes this instrument extremely accurate and repeatable
Controlled via a PC – SpectraMagicNX data software is used to control the device
Three diameter measurements – 3, 8, and 30mm aperture masks to fit any measurement need
Ability to measure transparency – using diffuse illumination/0 degrees viewing angle (d/0) geometry
Any application – pastes, solids, powders, liquids, and granular applications are possible
Top-port and transmission chamber – two ways of measuring items
