The Lovibond® Comparator 2000+ is an instrument for visually assessing and comparing a coloured sample against a set of coloured standards.

Available as single or multi parameter kits and using the guaranteed quality of Lovibond® Tablet Reagents, the Comparator 2000+ System is extremely versatile yet uncompromising in terms of precision and reproduceability of results.

Unique features include a prism enabling colour matching in a single field of view, and test discs containing fade-free glass colour standards to ensure long term stability and accurate colour matching.
Accessories such as portable and bench top Lighting Units allow consistent viewing conditions in any environment. Nessleriser Systems and longer path length cells increase the detection range to ppb levels and allow for higher disc resolution.

Over 400 individual discs are available for Water and Colour applications. Each disc contains fade free, chemical resitant glass colour standards for prolonged use in any environment.

For traceability and confidence, individual discs can be certified against master colour standards in the Lovibond® laboratory.

The full range of Lovibond® Comparator Discs for water analysis can be found on the Comparator 2000 Discs page. Please select the Parameter to be measured according to the alphabetical listings.
