Abstract

PURPOSE:To improve safety not only by warning the gas leakage of a warning level or above but alto by informing the level of the gas leakage below the warning level. CONSTITUTION:A detecting signal according to the density of a detecting gas from a gas detecting means A is inputted to a comparison means B and a level deciding means D. The comparison means B operates a warning means C when the level of the detecting signal exceeds the predetermined gas leakage warning level. The level deciding means D decides the level of the detecting signal by comparing it with plural predetermined levels and storing means E stores the level of the decided detecting signal. An informing means F informs the level of the detecting signal stored in the storing means E.
