The Comparator System 2000 is based on a versatile 2-field visual comparator with an optional lighting unit to guarantee correct lighting conditions for colour grading and colorimetric analysis.
The sample colour is visually matched in the comparator instrument against graded coloured glass filters in Lovibond® test discs. A wide selection of discs is available.Nessleriser systems are longer path length instruments for measuring unsaturated samples that are below the sensitivity of the standard Comparator 2000.
