Determination of Ozone in air.","description":"\u003ch3\u003eMacherey-Nagel, 90736, Ozone Test Sticks, Box of 12 Strips. Determination of Ozone in air.\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eThis test strip is for the determination of ozone in air. Ozone is a\ncolourless toxic gas. It is irritating to eyes and mucous membranes and can\ncause respiratory complaints. An ozone content of 180 micrograms\/ m3 is\nconsidered as critical value above which sensitive persons should avoid\nstronger physical exertion. The ozone values published by public media like\npress, radio or TV represent the ozone concentrations in the vicinity of the\nmeasuring stations. However, actual ozone values in other locations can\nconsiderably deviate from these published values due to meteorological and\nchemical influences such as wind, solar radiation, exhaust gases from vehicles\netc. For this reason a local measurement of ozone concentrations is\nrecommended. gradation of scale: less than 90, 90 -150, 150 - 210, greater\nthan 210 micrograms\/m 3 ozoneMethod of application: Place a test stick in the\nopen air, protected from wind. If necessary, fix the test stick with a piece\nof adhesive tape. After 10 minutes compare the test field with the colour\nscale on the container. Under standard conditions (101300 Pa, 20°C): 90\nmicrograms per meter cube ---\u0026gt; 0,0451 ppm, 150 micrograms per meter cube---\u0026gt;\n0,0752 ppm, 210 micrograms per meter cube ---\u0026gt; 0,105 ppm Interferences: Other\noxidizing reagents (e.g. chlorine) cause a similar colour change and simulate\ntoo high an ozone value. The measuring ranges are valid for a relative\natmospheric humidity of 30 to 60%. Humidity values below 30% can cause lower\nozone values, humidity above 60% higher values than actually present.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eOzone Test Sticks, Box Of 12 Strips\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003chr class=\"py-vbody\" style=\"display: none\"\u003e\n\n\n","brand":"Macherey-Nagel","offers":[{"title":"Default Title","offer_id":42683995816096,"sku":"B00S1UPL96","price":174.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0418\/7134\/3776\/products\/B00S1UPL96.jpg?v=1665790865","url":"https:\/\/dingoship.com.au\/products\/macherey-nagel-90736-ozone-test-sticks-box-of-12-strips-determination-of-ozone-in-air","provider":"DingoShip AU","version":"1.0","type":"link"}
