Model F

The Model F is a visual colorimeter designed to optimise the use of Lovibond^® glass filters in order to express colour in terms of Lovibond^®

Red, Yellow, Blue and Neutral. It is available in slightly varying  formats to meet the requirements of different applications and the  national and international standardising bodies which specify the  instrument in their official methods for colour measurement.

• Complete set of 11 racks containing permanently coloured glass filters for the Lovibond^® colour scale
• (Red  0.1 – 0.9, 1.0 – 9.0, 10.0 – 70; Yellow 0.1 – 0.9, 1.0 – 9.0, 10.0 –  70; Blue 0.1 – 0.9, 1.0 – 9.0, 10.0 – 40; Neutral 0.1 – 0.9, 1.0 – 3.0)
• Sample chamber liner with a white PVC reference
• Spare white reference
• A pair of spare bulbs
• 1 x 1″ & 1 x 5¼” rectangular fused glass cells

• Visual Colorimeter for Lovibond^® RYBN Scale

The Model F is a visual colorimeter designed to optimise the use of Lovibond^® glass filters in order to express colour 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 colour of light which is  either transmitted through, or reflected from, the sample. 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 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 colour of products which  are too bright to obtain a good colour match using Lovibond^® Red, Yellow or Blue glasses. The racks allow a visual colour match to be  found from the light from the sample and its colour can then be  expressed in Lovibond^® units.

• Assured Accuracy of Lovibond^® RYBN Colour 

Lovibond^® Tintometer^® is the only company that can guarantee accurate, validated Lovibond^® RYBN Colour readings.

• Easy Maintenance for Optimum Performance 

The Lovibond^® Tintometer is a precision optical instrument which should be kept clean  to preserve its accuracy, even in the harsh operating conditions often  encountered. This is why the Model F has been designed to allow easy  cleaning and maintenance with the minimum of cost and effort. The  instrument includes a white plastic liner in the sample chamber which  can be removed for cleaning if a spillage takes place. It can be  replaced at intervals to maintain the whiteness of the interior, an  essential feature for accurate colour matching.
Separate filters in  the racks also simplify cleaning and allow replacement of single glasses  (as opposed to complete racks) if required.

• Application Versatility 

The  Model F is an easy-to-use instrument with versatile application in  colour measurement of products which transmit light as well as opaque  solids, powders and pastes (an optional ‘solid’ sample accessory pack  may be required for colour grading of light-reflecting products).

• Compliance to International Standards 

It  is available in slightly varying formats to meet the requirements of  different applications and the national and international standardising  bodies which specify the instrument in their official methods for colour  measurement.
