Safety around source lamps
The source lamp is operated at high temperatures.
To prevent electric shock, disconnect the instrument from the power
source before replacing the lamp.
C A U T I O N
Burn hazard. Allow the lamp(s) to cool for at least 30 minutes before maintaining/
replacing them.

Chemical and biological safety

D A N G E R
Potential danger with contact with chemical/biological substances.
Working with chemical samples, standards and reagents can be dangerous.
Make yourself familiar with the necessary safety procedures and the correct
handling of the chemicals before use and read and follow all relevant safety data
sheets.
Normal operation of this device may require the use of chemicals or
samples that are biologically unsafe.
• Observe all cautionary information printed on the original solution
containers and safety data sheets prior to their use.
• Dispose of all consumed solutions in accordance with the local and
national regulations and laws.
• Select the type of protective equipment suitable to the concentration
and quantity of the dangerous material being used.
Overview of product
The LICO 690 and LICO 620 instruments are VIS spectral-photometers
with wavelength ranges from 320 to 1100 nm. The instruments can
perform a precise colorimetric analysis in accordance with ISO/ASTM
standards with a single measurement and display the result in the form
of classic color systems such as iodine, Hazen or Gardner color values.
The instruments support multiple languages.
The LICO 690 is supplied with 26 color value calculations, while the
LICO 620 is supplied with five color value calculations (Iodine color,
Hazen color, Gardner color, Saybolt color and ASTM D 1500 color
numbers).
The LICO 690 contains the following programs and operating modes in
addition to the color measurement: single wavelength mode, multi-
wavelength mode, wavelength scan and time scan mode. The digital
measurements are displayed in the dimensional units of concentration,
absorbance or % transmittance, making the LICO 690 universally
suitable for lab analysis.
