<p>PURPOSE:To obtain the ozone decomposing apparatus decomposing zone always perfectly by measuring the ozone concn. in the activated carbon layer in the ozone decomposing apparatus to detect the life of activated carbon. CONSTITUTION:A sampling pipe 10 is inserted into the activated carbon layer 2 of the ozone decomposing apparatus and a gas in the activated carbon layer 2 is sent to a densitometer 7 from a flexible pipe 12 and a gas conduit 11 to measure ozone concn. in said gas. In this case, an alarm means is preliminarily set to the ozone densitometer 7. By this structure, because the life of activated carbon can be previously informed or warned, ozone is not discharged and environmental pollution is prevented.</p> |
