Nasa Ozone Watch: Dobson Unit facts

· The Dobson Unit is the most common unit for measuring ozone concentration. One Dobson Unit is the number of molecules of ozone that would be required to create a layer of pure ozone millimeters thick at a temperature of 0 degrees Celsius and a pressure of 1 atmosphere (the air pressure at the surface of the Earth). Expressed another way, a column of air with an ozone …

OZONE DESTRUCT UNIT

Ozone destruct units are an essential safety measure when dealing with ozone applications. Exhaust gases from processes where ozone has been used invariably contain residual amounts of un-reacted ozone and before this exhaust can be vented into the atmosphere, it is necessary to decompose the ozone to trace levels. Ozone destructs safely destroy excess ozone that is present in the inlet air ...
