These ozone generators usually produce ozone from ambient air that is blown across a corona or UV device that produced ozone from the ambient air blown through the generator. <\/span><\/span><\/p>\n<p><span style=\"color: #000000\"><span style=\"font-size: small\">Ozone output is normally measured in mg\/hr. To calculate mg\/hr of ozone produced we must know the mass of ozone and the volume of air. These calculations along with the equipment and methodology required are listed below.<\/span><\/span><\/p>\n<p><span style=\"color: #000000\"><span style=\"font-size: small\">It is important to understand and realize that the quality of ambient air, temperature of the air, <\/span><\/span><span style=\"color: #000000\"><span style=\"font-size: small\">relative humidity of the air<\/span><\/span><span style=\"color: #000000\"><span style=\"font-size: small\">, and cleanliness of the UV light or Corona discharge device are very critical. As these parameters may change over time ensure you quantify and qualify each parameter before beginning this test. Also understand that manufactures of these ozone generators may not ever test ozone production, or may test production with a wide variety of ambient temperatures, <\/span><\/span><span style=\"color: #000000\"><span style=\"font-size: small\">relative humidities<\/span><\/span><span style=\"color: #000000\"><span style=\"font-size: small\">, and other factors.<\/span><\/span><\/p>\n<p><span style=\"color: #339966\"><span style=\"font-family: Liberation Sans,sans-serif\"><span style=\"font-size: x-large\"><b>Equipment required:<\/b><\/span><\/span><\/span><\/p>\n<ul>\n<li><a href=\"https:\/\/www.oxidationtech.com\/products\/ozone-monitors\/uv-analyzer\/uv100-ozone-analyzer.html\"><span style=\"color: #000000\"><b>Ozone Meter<\/b><\/span><\/a><\/li>\n<li><span style=\"color: #000000\"><b>Monometer<\/b><\/span><\/li>\n<li><span style=\"color: #000000\"><b>Flow Tube<\/b><\/span><\/li>\n<\/ul>\n<p><span style=\"color: #000000\">\u00a0<span style=\"font-size: small\">An <b>ozone meter<\/b> will be required to measure ozone concentration in the air leaving the ozone generator. This must have a sample pump to draw a sample of gas from your flow tube into the monitoring device. This will provide the most accurate ozone measurements without disrupting your air flow. Ideally a UV based ozone analzyer will be used to measure ozone levels due the greater precision and accuracy available. However, there are some ozone meters available using electrochemical or HMOS sensor cells that can pull a gas sample into the sensor and provide reasonable accuracy. For the best accuracy in ozone production choose the most accurate ozone meter possible.<\/span><\/span><\/p>\n<figure style=\"width: 129px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.oxidationtech.com\/media\/catalog\/product\/cache\/5\/small_image\/210x\/9df78eab33525d08d6e5fb8d27136e95\/u\/v\/uv-100_front_image.png\"><img loading=\"lazy\" decoding=\"async\" id=\"product-collection-image-750\" src=\"https:\/\/www.oxidationtech.com\/media\/catalog\/product\/cache\/5\/small_image\/210x\/9df78eab33525d08d6e5fb8d27136e95\/u\/v\/uv-100_front_image.png\" alt=\"UV-100 Ozone Analyzer for sale or rent\" width=\"129\" height=\"129\" \/><\/a><figcaption class=\"wp-caption-text\">UV-100 Ozone Analyzer<\/figcaption><\/figure>\n<p><span style=\"color: #000000\"><span style=\"font-size: small\">The specific ozone analyzer we recommend to use for this testing is the <a href=\"https:\/\/www.oxidationtech.com\/products\/ozone-monitors\/uv-analyzer\/uv100-ozone-analyzer.html\">UV-100 Ozone Analyzer.<\/a>\u00a0 This is available<a href=\"https:\/\/www.oxidationtech.com\/products\/ozone-monitors\/uv-analyzer\/uv100-ozone-analyzer.html\"> for sale<\/a>, or <a href=\"https:\/\/www.oxidationtech.com\/products\/rent-ozone\/uv-100-rental.html\">for rent for shorter term needs.<\/a><\/span><\/span><\/p>\n<p><span style=\"color: #000000\"><span style=\"font-size: small\">A <b>Monometer<\/b>is used to measure airflow by measuring the velocity of airflow in your flow tube.
