The CR-5 is a very versatile bench-top colorimeter to measure the colour 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 Flavours & Fragrances, Foods, Chemicals, Pharmaceuticals and Plastics.

The CR-5 can work stand alone thanks to the large colour 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.

Very intuitive routine work is guaranteed by features such as automatic calibration, Operation Wizard and support in seven languages.
