Visual Colorimeter for Lovibond^® RYBN Scale
The Model F is a visual colorimeter designed to optimize the use of Lovibond^® glass filters in order to express color in terms of Lovibond^® Red, Yellow, Blue, and Neutral.

Two Adjacent Fields of View
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.

Easy Colour Comparison
The Lovibond^® glasses are introduced into the comparison field by a simple system of sliding racks, allowing you to compare the color of light which is either transmitted through or reflected from, the sample. The racks are varied until a visual color match is found for the light from the sample and its color can then be expressed in Lovibond^® units.

Excellent Colour Matching
A series of neutral glasses in racks is also supplied; these can be introduced into the sample field to 'dull' the color of products that are too bright to obtain a good color match using Lovibond^® Red, Yellow or Blue glasses. The racks allow a visual color match to be found from the light from the sample and its color can then be expressed in Lovibond^® units.

Applications- Edible oils,  Glycerine and Fragrances, Tapioca, Soap noodles
