Multi-parameter colorimeters

The LICO 620 and LICO 690 colorimeters are ideal for professional colour measurements of clear, transparent liquids with reference beam technology.
  • Automatic cuvette identification
  • Serves as a quality assurance method for solvents, paints and pharmaceuticals
  • High level of measurement reliability through a comprehensive set of test aids
  • Simple integration into the laboratory network through Ethernet connection
  • Easy to change cuvette adapter
LICO 620 measures five colour scales.
LICO 690 measures more than 25 colour scales. Exact colour calculations which conform to several DIN-ISO-ASTM standards or AOCS methods are completed with only one measurement. Traditional visual colour values like the iodine colour value, Hazen or Gardner are displayed as well as modern colour systems, e.g. CIE-L*a*b* or colour measurements corresponding to European or US pharmacopoeia. Transmission, extinction measurements and wavelength scans are possible as well. Intuitive operation through a high resolution touch screen makes routine measurements easy. Measurement results can easily be transferred to an existing laboratory network via Ethernet interface.
All visual colour ratios are calculated for standard light chart C and 2° standard observers in accordance with DIN 5033. Colorimetric colour values can be switched to light type A, C, D65 and 2° or 10° standard observers.
Delivery information: Supplied with power supply, printed basic user manual, CD with full user manual in 4 languages, 10 mm cell adapter and dust cover.
