Chroma meter CR-5 (A laboratory instrument for food & chemical application)
Affordable And High Performance Benchtop Colorimeter
Konica Minolta Chroma Meter CR-5 built and designed base on CM-5 spectrophotometer that offers offers a fantastic price to performance ratio, particularly for QC measurements of liquids. Like the CM-5 the CR-5 can operate independently of a PC and features a color screen for enhanced usability.
Chroma meter CR-5 is a very versatile bench-top colorimeter to measure the color of solid, pasty granular and liquid samples either in reflectance or transmittance. The top-port concept, offering various aperture sizes, allows measurement of almost any kind of samples. The CR-5 is thus the perfect all-rounder laboratory instrument for applications such as Flavors & Fragrances, Foods, Chemicals, Pharmaceuticals and Plastics.
The CR-5 can work stand alone thanks to the large color screen and extensive firmware offering all major colorimetric systems including industry specific indices to measure transparent liquids such as Gardner, Hazen/APHA, Iodine, European and US Pharmacopoeia. In combination with the optional software SpectraMagic NX many more indices are available.
Applications
Food | Plastic | Cosmetics | Ceramic | Granular Material | Paste | Liquid |Powder samples | Education | Research Institiution etc.
Chroma Meter CR-5
- Includes aperture sizes, 3mm, 8mm, and 30mm, to evaluate the color and appearance of samples very small to large in size
- Equipped with a top-port area for measuring opaque samples, as well as a transmittance chamber for measuring transparent and translucent samples
- Pass/fail assessments immediately determines if the sample meets the defined standard or target color
- Instrument is calibrated automatically with each start up to maintain its high accuracy and performance
- Large color LCD screen displays data and graphs clearly, including color values.
- Provides an Operation Wizard to guide users through instrument set up and measurement use
- Individual instrument settings and measurement data can be stored to eliminate confusion between multiple users
- Various industry-specific indices are stored in the instrument, including Gardner, Hazen/APHA, Iodine Color Number, US and European Pharmacopoeia, to meet application needs quickly and more effectively
