Lovibond® Tintometer® is at the forefront of technical innovation for the colour measurement of liquids and solids. The product range incorporates both visual and automated instruments. The Tintometer Ltd enjoys a traditional history but an even more innovative future. The company was founded in 1885 by Joseph Lovibond, a prominent brewery owner who developed the ‘colorimeter’ as a means of ensuring the quality of his beer. By 1893 he had perfected his research and introduced the first instruments. Much has developed since then.
Colour measurement in the brewing industry is an important part of the quality control measures that are put in place to ensure consistency of the product.
In cases such as caramel production the colour is indicative of the market value of the product.

Scales and Values
Grading techniques are widely used to assess product colour by comparison with a representative series of fixed colour standards.
For many product types, a characteristic set of standards was agreed and adopted to aid colour control and the communication of colour specifications; the result is a selection of traditional colour grading scales that have been adopted as industry standards and are still in common use today.
Your Colour Scale requirement determines your instrument choice. We would be delighted to offer advice as to the correct colour scale and thus instrument choice for your application. Please do not hesitate to contact us.
- Alpha Amylase in Malt
- The American Society of Brewing Chemists (ASBC) procedure for determining alpha-amalyse in malt uses dextrinization. In the presence of beta- amylase, alpha-amylase converts soluble starch to the sugar maltose
- Instruments required: Lovibond® Comparator. Alpha Amylase disc 4/29, 2x DB424 13.5mm Cells
- ASBC Colour
- American standard for colour grading of beers; related to the EBC Colour scale
- Instruments required – PFXi -195/4
- EBC (European Brewing Convention)
- Recognised method for colour grading of beers, malts and caramel solutions as well as similarly coloured liquids
- If the sample falls outside this range (e.g. concentrates, syrups) then sample dilution and/or a different path length cell can be used to bring the reading within the EBC range.
- Please note, the EBC colour scale is based on a sample path length of 25mm therefore, when cells of different path lengths are used or when dilutions are made, it is essential that these factors are taken into account, the correct adjustments made and full details recorded for future reference.
- Instruments that can be used: PFXi-195/4 or AF330 or EBC ColorPod or EBC Comparator
- Series 52 (Brown) Scale
- Original Lovibond® Brown colour scale now currently used for the colour grading of whisky, honey and similarly coloured liquids or syrups
- EBC Colour has largely superseded it for the grading of beers in Europe but it is still used for beers in the US and for whiskies. It is sometimes referred to as degrees Lovibond® in the US brewing industry
- It is also suitable for sugars, solutions and syrups
- Instruments that can be used: PFXi-195/4 or PFXi-195/7
- A Series of colour standards for grading the colour of Whisky based on the Lovibond® Brown Scale.
