Conformance filter sets allow quick and simple conformance checks on Lovibond^® instruments. Each filter set is supplied with a Certificate of Conformity that confirms they have been manufactured under the control of our ISO 9001: 2000 Quality Management System.

Conformance filters are assigned a nominal value and Lovibond Tintometer always endeavours to match this value as closely as possible. On occasion, because of the unique manner of the glass making process, it may not be possible to match the requested values exactly. The values achieved and the performance tolerances expected will, of course, always be reported.
