System components:
Comparator instrumentto bring the sample and the glass filters together for colour matching
Lighting unit (optional) to ensure constant viewing conditions for colour matching
Colour grading disc containing a series of glass filters, graded to give direct colour values
Sample container of the required path length

Certification & Calibration of Lovibond® Colour Grading Discs
Customised Colour Standards
Colour Grading Kits based on the Comparator 2000 System
Colour Grading Discs for use with the Comparator 2000 System
Colorimetric Chemical Analysis Discs for use with the Comparator 2000 System

For specific colour control requirements Tintometer Ltd can also manufacture customised glass filters, which are matched to samples provided, usually representing the 'ideal' colour and acceptable colour limits or a series of product related colours.

Using the Lovibond® Comparator 2000 System

	1. Follow the test method for sample preparation, adding the specified reagent to a known volume of sample in the appropriate sample container.
	2. Insert the Lovibond® test disc into the comparator instrument.
	3. Place the sample container in the right hand comparator compartment, and, if specified in the test method, a cell containing a blank of water or untreated sample in the left hand side.
	4. Using standardised lighting, rotate the disc until the closest colour match with the sample is obtained.
	5. The value will be shown in the window in the comparator instrument.
