How can you tell the level of Ozone?

There are a number of mechanical methods available, the most common and effective being the Draeger tube, but the simplest, least expensive and very reliable method is to use your nose. Residual ozone becomes apparent to sensitive humans in the range of .01 - .03 ppm, or well below the permissible levels for continuous exposure. As noted previously, this residual ozone is extra ozone that is not required to kill bacteria etc. Adjustment of the rheostat is all that is required.

NEW PORT RICHEY -- More than 2,000 plants will be squeezed into a small space about 25 by 50 feet at a hydroponics garden being built at the nonprofit food bank, Volunteer Way.

The ever rising cost of food inspired the food bank to start growing some of its own produce, Lester Cypher, the CEO of Volunteer Way, said today.
