Warsash Scientific present StellarNet’s EPP2000-CXR Spectrocolourimeter, a low cost instrument for any colour measurement application.
The StellarNet Spectrocolourimeters measure the colour of solid and liquid samples using a fiber optic reflectance probe, fixture, dip probe, or cuvette holder.
The EPP2000-CXR Spectrocolourimeter has consistent resolution throughout 280-900nm and utilises a concave grating, which translates to low stray light levels because there are no mirrors in its optical bench.
The spectrometer is engineered with no moving parts resulting in shock proof durability and permanent alignment.
The EPP2000-CXR Spectrocolourimeter offers better reliability, accuracy and ruggedness. The EPP2000-CXR Spectrocolourimeter is applicable for colour measurements of food, beverages, industrial and home liquids, textiles, plastics, pharmaceuticals and raw materials.
The SpectraWiz software is included to provide CIE 1976 L* a* b* (CIELAB) colour coordinate data for measurement and tolerancing. The L* (L star) is a measure of Brightness. The a* and b* are the colour coordinates that range from -90 to +90 in the CIELAB colour space "circle". For a* (a star), -90=green and +90=red. For b* (b star), -90=blue and +90=yellow.
To perform colour tolerancing, a standard sample is measured and saved for future comparisons. Delta E* is then calculated to show the colour differences with other samples. Double beam and multi-beam colour monitors for continuous industrial process monitoring are configurable by adding additional channels.
