Sulphur Dioxide Generator
A simple apparatus developed for air pollution studies and sulphur dioxide corrosion tests on metals and non-metals. It produces SO2 air mixture by the controlled action of sulphuric acid on sodium sulphite. Solutions of acid and sodium sulphite are fed to the reactor at precisely controlled rate where sulphur dioxide gas is liberated in the reaction loop. The flusher evacuator unit, equipped with acid resistant micro vacuum pump, sucks up and dispenses out the sulphur dioxides gas generated in the process. The unit works on 220V 50Hz AC mains.
