The Model F is a visual colorimeter designed to optimise the use of LovibondÂ® glass filters inorder to express colour in terms of LovibondÂ® Red, Yellow, Blue and Neutral.
It is arranged with two adjacent fields of view, seen through the viewing tube, so that the product in the sample field and a white reflective surface in the comparison field are observed side by side, suitably illuminated.
The LovibondÂ® glasses are introduced into the comparison field by a simple system of sliding racks, allowing the user to compare the colour of light which is either transmitted through or reflected from the sample with that transmitted through the glasses.
A series of neutral glasses in racks is also supplied; these can be introduced into the sample field to dull the colour of products which are too bright to obtain a good colour match using LovibondÂ® Red, Yellow or Blue glasses. The racks are varied until a visual colour match is found for the light from the sample and its colour can then be expressed in LovibondÂ® units.
We are the only company that can guarantee, accurate, validated LovibondÂ® RYBN Colour readings.
