Automatic Plant Oil Oxidation Stability Index (OSI)Accordance With 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.
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.
199 groups of historical data can be stored for the convenience of query;
|Results output||at the same time can be equipped with U disk output function, output to the PC for long-term storage|
equipped with special calculation software, it can automatically calculate the oxidation stability time.
real time display of oil oxidation process and conductivity in induction period
the instrument itself has a color display screen, which can display the temperature of each heating module, gas flow rate, measuring cell status, conductivity value of each measuring position, etc
