Comparator System 2000+ 1 * 1 Item
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+.
The integrated prism presents the glass standard discs and the coloured sample in the same field of vision, which allows for discrimination and matching of colours
The prism is ultrasonically sealed to prevent contamination of the optics
Each test disc is equipped with glass filters which guarantee a stability of colour, which do not fade and which can be changed easily without having to open the apparatus
Allows for the compensation of water samples that are turbid or tinted
Each comparator is available as a natural daylight option or can be used with the standardised Daylight 2000 lighting unit or a portable lighting unit
