Nessieriser Systems

We can't find products matching the selection.

Lovibond® Nessleriser Systems are based on the Comparator 2000+, an instrument for visually assessing and comparing a coloured sample against a set of coloured standards. Nessleriser Systems use a longer path length and are therefore capable of measuring concentrations below the sensitivity of the standard Comparator 2000+ tests.


Like the Comparator 2000+ the Nessleriser Systems include a prism to allow colour matching in a single field of view, and discs with unique fade-free glass colour standards.


Systems use either natural light or an electronic daylight unit for a consistent light source.


2150 systems use cells with a path length of 113mm and are compatible with any Comparator 2000+ disc with the prefix "N"


2250 systems use cells with a path length of 250mm and are compatible with any Comparator 2000+ disc with the prefix "C"


The AF327 system is specifically designed for Hazen (Platinum-Cobalt) testing to the ASTM D1209 standard and uses a path length of 288mm.
