T21121 Oil Oxidation Stability Tester

The ST149 fully automatic Oil Oxidation Stability Index (OSI) is designed and manufactured in strict accordance with GB/T21121-2007 for the determination of animal and vegetable oil oxidation stability (accelerated oxidation test). It is controlled by a microcontroller, displayed on a LCD screen, automatically outputs results, and prints automatically.Fully automatic bacon and sausage accelerated oxidation stability tester

OSI(Oxidative Stability Index), During the measurement, a certain flow rate is introduced into the oil sample at a certain temperatureairAccelerate the oxidation of glycerol fatty acids and produce volatile organic acids. The air brings volatile organic acids into a conductive chamber, and the water inside the chamber 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 calledOSI time.Fully automatic bacon and sausage accelerated oxidation stability tester

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.
