2.Automatic Oil Oxidation Stability Tester Oil oxidation stability tester Oxidation stability testerH18417

The fully automatic Oil Oxidation Stability Index (OSI) is designed and manufactured in strict accordance with GB/T 21121-2024/IS0 6886:2016, replacing GB/T 21121-2007 for the determination of animal and plant oil oxidation stability (accelerated oxidation test). It is controlled by a microcontroller, displayed on a LCD screen, automatically outputs results, and prints.

OSI(Oxidative Stability Index), When measuring, 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 volatile organic acids into a conductive chamber, and the indoor water dissolves the volatile organic acids, ionizes them, and changes the conductivity of the water. The computer continuously measures the conductivity of the conductive chamber, and when the conductivity rises sharply, it indicates the end of the induction period. The period before this is called OSI time.

Controlled by a microcontroller, it can also draw a sample time conductivity curve and automatically calculate the stability time of oil oxidation; The instrument itself has a sample measurement switch and status display.
