2. GENERAL DESCRIPTION
The
MI490
is an auto-diagnostic portable microprocessor meter. It has an advanced
optical system based on a special tungsten lamp and a narrow band interference filter
that allows most accurate and repeatable readings. All instruments are factory calibrated.
The auto-diagnostic feature of this meter ensures always optimal measurement
conditions to ensure most precise readings. The light level is automatically adjusted each
time a zero-measurement is made, and the temperature of the lamp is controlled to avoid
overheating.
Significance of Use
Peroxides are the primary products of oil oxidation. Their identification gives useful
information about oil conservation and rancidity.
MI490
allows fast and simple analyses
of peroxides in oil in accordance with the EC 2568/91 method.
