Lovibond/Tintometer Color Measurement | ||||||||

||||||||
| In the 1860s, Joseph
Lovibond, the founder of The Tintometer Ltd, developed the original Lovibond
Color system, which was based on a calibrated series of red, yellow and
blue glas color standards. Today companies throughout the world use
Lovibond colorimeters in the analysis of products such as edible and industrial
oils, fuel oils, chemicals, coatings and beverages. Over the years
the Lovibond brand has become the hallmark for color measurement in processing
industries, recognised by major international standardising bodies, who
quote our equipment in their specifications for color management (in particular
ASTM standards and AOCS methods). Tintometer’s unparalleled knowledge
is embodied into the Lovibond range of instruments, from the visual comparators
for grading single color scales through to flexible, full-scale spectrophotometric
instruments for objective colorimetry and data analysis.
The range of Lovibond colorimeters covers the key color scales and color values that are used by industry for color control: | |||||||||
