主要特点

These durable, portable systems allow you to make quick visual comparisons between your sample and a range of stable colored glass standards on a disc. Battery operated illuminator offers flexibility for laboratory, plant, or field color grading. With the two-section field of view, the sample transmittance is directly compared with individual colored glass standards on a test disc.

The comparator is ideal for light-colored samples with visual color (pathlength up to 40 mm); an illuminator is added to systems for measuring unsaturated samples requiring a longer pathlength.
