Lovibond: Precise color analysis of liquid and solid samples
Evaluate the color of your products with Lovibond
Lovibond , and other materials using standardized reference scales. Thanks to its accuracy and reproducibility, this technique is essential for industries requiring rigorous color control, particularly in the food, petrochemical, and pharmaceutical sectors.
Lovibond ensures product compliance with international standards and provides consistent visual quality for consumers and end users .
How does Lovibond's color measurement work?
Lovibond relies on a precise color assessment using a combination of optical filters and standardized light sources. Its principle is based on several steps:
- Sampling – The liquid or solid sample is placed in a cuvette or measuring container.
- Standardized lighting – A specific light source illuminates the sample to minimize variations due to environmental conditions.
- Comparison with colorimetric filters – The intensity and hue of the sample are compared to reference filters, often aligned to scales such as Lovibond RYBN (Red, Yellow, Blue, Neutral) or the Gardner scale.
- Reading and interpreting the results – The values obtained are translated into numerical indices allowing for the precise classification of the color of the sample.
This method guarantees repeatable and comparable measurements between different production batches.
