COMPARATORS

  • Lovibond model 2000

    The comparitor consists of a robust pocket case made of solvent and acid-resitant plastics, which accomodates a comparitor disc containing a range of colour standards and two sample cells of up to 40mm light path length. Measurement is made by comparison of a sample of the test solution against a disc representing the colour range produced by known concentrations of the test material. Viewing is carried out by transmitted light which may be north daylight or from the white light cabinet available as an accessory.
