Automatic Oil Oxidation Stability Tester ISO 6886 Accelerated
Oxidation Test
ST149 automatic plant oil oxidation stability index (OSI) is
designed and manufactured in strict accordance with GB/T 21121-2007
determination of oxidation stability of animal and vegetable oils
(Accelerated oxidation test). It is controlled by a single chip
microcomputer and displayed by a liquid crystal LCD. The results
are automatically generated and printed.
ISO 6886 Oxidative Stability Test Apparatus for Animal and
Vegetable Fats and Oils
OSI (oxidative stability index): during the determination, hot air
at a certain temperature is introduced into the oil sample to
accelerate the oxidation of glycerol fatty acids and produce
volatile organic acids. The air brings the volatile organic acids
into a conductive chamber, and the indoor water dissolves the
volatile organic acids and ionizes ions, thus changing the
conductivity of the water. The computer continuously measures the
conductivity of the conductive chamber. When the conductivity rises
sharply, it indicates the arrival of the end of the induction
period, and the period before that becomes OSI time.
Controlled by single chip microcomputer, the time conductivity
curve of the sample can be drawn and the oxidation stability time
of the oil can be calculated automatically; The instrument has
sample measurement switch and status display.
