The Comparator System 2000+ is a precise and general purpose colorimetric system for water testing. It is a high quality instrument for visually matching the intensity of the colour of the sample with Lovibond glass filters. It includes an adjustable cell compartment for samples in cells of up to 40 mm in path length. Nessleriser 2150 and the 2250 are longer path length instruments for matching a column of a sample in a Nessler cylinder with Lovibond glass filters. They are designed for measuring concentrations that are below the sensitivity of the Comparator 2000+.
