Lovibond® Nessleriser Systems, Pt-Co/Hazen/APHA Scale
For colour grading of clear, light yellow liquids such as clear oils, chemicals, petrochemicals and water. Each system covers a set measuring range and includes:
-A visual comparator instrument with a long path length, ensuring good sensitivity and accuracy when grading pale coloured samples.
-A selection of Pt-Co/APHA colour standards; stable-coloured glass filters in test discs, which have been precalibrated to give direct Pt-Co Colour readings over set measuring ranges.
-A standardised bench-top light source to ensure constant and uniform lighting conditions for colour matching and therefore consistent and accurate readings.
-Nessler cylinders of the appropriate path length.
