Iodine Number is the most valuable parameter for differentiating or identifying oils and readily serves to indicate the group to which the oil belongs. Presently, Iodine Number is being determined using wet chemical analysis in which number of reagents, glasswares, chemical laboratory and analytical chemist is required. The instrument developed by CSIO is based on measurement of change in potential across the sensing and reference electrodes when immersed in a mixture of test reagent and oil. The LCD display is a direct measure of Iodine Number. The salient features of Iodine Value Meter are: Portable and low cost, direct display of iodine number, reproducible results, low cost of analysis, readymade test reagents and easy to operate. The technology would be useful for the determination of Iodine number of oils, fats and unsaturated compounds. The indigenous production of this instrument would meet the demand in the country
