"Vaiseshika" Digital Iodine Value meter Type : 7706
Description
It has been designed for the Edible Oil Industry to determine the Iodine Value Number of commonly available oils like Coconut Oil, Groundnut Oil, Sunflower Oil, Soyabean Oil, Mustard Oil and other similar edible oils. This instrument has been designed and manufactured in technical collaboration with the Central Scientific Instruments Organisation, Chandigarh under the Technology Modernization and Upgradation Mission for Oil and Pulses Industry launched by the Ministry of Agriculture, Government of India, New Delhi.
IODINE NUMBER
Iodine Number is the number of centigrams of iodine absorbed by one gram of oil or fat.
Iodine Number is the most valuable parameter for differentiating or identifying oils and readily serves to indicate the group to which the oil belongs. The unsaturated acids of oleic, linolenic, or les saturated series, as well as their glyceryl esters, absorb halogens to form mainly addition products. One molecular weight of triglyceride olein absorb 6 atomic weights of Iodine would absorb 18 atomic of iodine.

Principle
The instrument 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.
Working
Fifty ml of the known strength ICI solution is taken in glass stoppered flask and 0.7g of oil ia added to it. After 30 minutes the observation is taken. To measure iodine value, the reading on LCD is set to zero in I – V mode using ICI solution. Electrodes are cleaned and again dipped in test solution, LCD display is a direct measure Iodine Number of an oil.
Applications
Iodine number of oils and fats.
Iodine number of unsaturated compounds.
Iodine number of charcoal
Advantages
Presently in the Oil and Pulses Industry the Iodine Number is being determined using wet chemical analysis in which number of reagents like chloroform, halogen chloride, glacial acetic acid, potassium iodide, hydrochloric acid, sodium thiosulphate solution and glasswares, chemical laboratory and analytical chemist is required. The entire existing process of estimation of Iodine Number is very cumbersome. This Iodine Value Meter is a simple, low cost, portable and easy-to-operate instrument which can give the value of Iodine Number directly on digital display in an electronic instrument.
