DetailsThe Model F is a visual colorimeter designed to optimise the use of Lovibond® glass filters in order to express colourof the sample in terms of Lovibond® Red, Yellow, Blue and Neutral. It can be used for colour measurment of products which transmit light as well as for opaque solids powders and pastes. Typical applications include including fats and fatty oils, bleached lac, liquid chemicals and pharmaceuticals.Using the viewing tube the observer can compare the light which is transmitted through or reflected back from the sample and the light transmitted through the Lovibond glass filter which is adjacent in the field of view. The Lovibond glasses are in a rack system to allow the observer to easily change the glass and determine the colour match. A series of neutral glasses are also supplied to adjust the ‘brightness’ or dull the colour to get a good comparison with filter glasses.

These tube furnaces can be used for horizontal (RSH) or vertical (RSV) operation. The split-type design makes it easy to change the working tube. It allows
for a comfortable exchange of various working tubes (e.g. working tubes made of different materials).
Using a wide range of accessories, these professional tube furnaces can be optimally tailored for your process. By adding different gas supply packages,
you can work in a protective gas atmosphere, with gases or in a vacuum. In addition to the convenient standard controllers, modern PLC controls can also
be used to control the process.Standard Equipment
