How does a tintometer work?
The Tintometer uses a series of gradient red-, yellow-, blue-, and neutral-colored glasses. 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.
What is lovibond Colour?
The Lovibond® RYBN colour scale is optimised for the colour measurement of clear (but coloured) liquids. In the 1890’s, Joseph Lovibond, the founder of The Tintometer Ltd, developed the original Lovibond® Scale, based on a calibrated series of red, yellow, blue and neutral glasses.
How does Lovibond comparator work?
The device is used to determine the color of liquids. A sample is put in a glass tube. The tube is inserted in the comparator and compared with a series of coloured glass discs until the nearest possible match is found.
How do you measure color?
The measurement of colour is known as colorimetry. A variety of instruments are used in this field. The most sophisticated, the spectrophotometers, analyze light in terms of the amount of energy present at each spectral wavelength.
What is the unit of colour?
A unit of color is the color produced by 1 mg/L platinum in the form of chloroplatinum ion. The color values measured by comparison with the platinum-cobalt standards can be expressed as PCU, Pt-Co, APHA, or Hazen units depending on the specific procedures.
How do you use a color comparator?
General Requirements
- Put the color disc on the center pin in the color comparator box (numbers to the front).
- Use sunlight or a lamp as a light source to find the color match with the color comparator box.
- If the color match is between two segments, use the value that is in the middle of the two segments.

Does a colorimeter generate lab values?
A colorimeter is usually a filter based instrument and as such is does not generate precise Lab values. The Lovibond filters are however a well-designed and standardized product and each filter set is graded to conform to a published R,G,B colour identity scale.
What is the model of the colorimeter F?
Join ResearchGate to ask questions, get input, and advance your work. The model F is a high specification colorimeter based on the visual comparison of coloured samples with coloured glass filter combinations. A colorimeter is usually a filter based instrument and as such is does not generate precise Lab values.
