The Model F is a versatile visual colorimeter for measuring the colour of samples in terms of Lovibond units.  The user simultaneously compares the colour of light that is transmitted through from the sample with that transmitted through a series of glass colour filters in 3 primary colours - red, blue and yellow.  The slides are adjusted until a visual colour match is found for the light from the sample and the colour is then expressed in Lovibond RYBN Colour units. The Model F is available in two versions to meet the requirements of different applications and the standardising bodies that specify the instrument in official test methods for colour measurement.
