It tends to stay where it is.<\/li>\n<li data-canvas-width=\"270.57674\">Ozone tends to cling to rough surfaces such as fabrics and breaks down (converts back to oxygen) when passing through restricted and obstructed passageways.<\/li>\n<li data-canvas-width=\"359.3839999999999\">Ozone reverts back to oxygen with a &#8220;half life&#8221; (time to go to half of its original concentration) typically of 10-30 minutes.<\/li>\n<li data-canvas-width=\"380.6531199999999\">Ozone can be confused by instrumentation with other oxidizing gases such as chlorine compounds, acid fumes, and oxides of nitrogen (NOx). Strong &#8220;reducing&#8221; gases, such as vapors of alcohol and\u00a0 solvents, can reduce the apparent concentration of ozone.<\/li>\n<li data-canvas-width=\"73.16604000000001\">Ozone has a sweet smell, but the odor threshold varies widely by the person and by ambiental conditions. Therefore &#8220;smell&#8221; is not a reliable test for the presence or concentration of ozone.<\/li>\n<\/ul>\n<div data-canvas-width=\"303.68000000000006\"><\/div>\n<div data-canvas-width=\"303.68000000000006\"><strong>The important measurement is:<\/strong><\/div>\n<div data-canvas-width=\"158.40116999999998\">What is the ozone concentration at the breathing level where room occupants will be?<\/div>\n<div data-canvas-width=\"467.59498999999994\">For ozone introduced via HVAC systems with good room air circulation, the alternate point of measurement is near the entrance to the return air duct.<\/div>\n<div data-canvas-width=\"467.59498999999994\"><\/div>\n<div data-canvas-width=\"467.59498999999994\"><strong>Suggested ozone Monitors:<\/strong><\/div>\n<div data-canvas-width=\"467.59498999999994\">\n<figure style=\"width: 109px\" class=\"wp-caption alignnone\"><a title=\"A-21ZX Ozone Sensor\" href=\"https:\/\/www.gas-sensing.com\/portable-monitors\/a21-ozone-sensor.html\"><img loading=\"lazy\" decoding=\"async\" id=\"image\" class=\"\" title=\"A-21ZX Ozone Sensor\" src=\"https:\/\/www.gas-sensing.com\/media\/catalog\/product\/cache\/1\/image\/9df78eab33525d08d6e5fb8d27136e95\/a\/-\/a-21zx.png\" alt=\"A-21ZX Ozone Sensor\" width=\"109\" height=\"131\" \/><\/a><figcaption class=\"wp-caption-text\">A-21ZX Ozone Sensor<\/figcaption><\/figure>\n<\/div>\n<div data-canvas-width=\"467.59498999999994\">\n<figure style=\"width: 114px\" class=\"wp-caption alignnone\"><a title=\"C-30ZX Ozone Monitor\" href=\"https:\/\/www.gas-sensing.com\/fixed-mount-monitors\/c30zx-ozone-monitor.html\"><img loading=\"lazy\" decoding=\"async\" id=\"image\" title=\"C-30ZX Ozone Monitor\" src=\"https:\/\/www.gas-sensing.com\/media\/catalog\/product\/cache\/1\/image\/9df78eab33525d08d6e5fb8d27136e95\/c\/-\/c-30zx_ozone_monitor.png\" alt=\"C-30ZX Ozone Monitor\" width=\"114\" height=\"115\" \/><\/a><figcaption class=\"wp-caption-text\">C-30ZX Ozone Monitor<\/figcaption><\/figure>\n<figure style=\"width: 145px\" class=\"wp-caption alignnone\"><a title=\"OS-6 Ozone Controller\" href=\"https:\/\/www.gas-sensing.com\/fixed-mount-monitors\/os6-ozone-controller.html\"><img loading=\"lazy\" decoding=\"async\" id=\"image\" title=\"OS-6 Ozone Controller\" src=\"https:\/\/www.gas-sensing.com\/media\/catalog\/product\/cache\/1\/image\/9df78eab33525d08d6e5fb8d27136e95\/o\/s\/os-6_ozone_controller.png\" alt=\"OS-6 Ozone Controller\" width=\"145\" height=\"137\" \/><\/a><figcaption class=\"wp-caption-text\">OS-6 Ozone Controller<\/figcaption><\/figure>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Measuring Ozone in an Occupied Room ozone concentrations can vary greatly at various locations, and the concentrations are often highest in unexpected places.
