This tube reacts with ozone to shift from blue to pale yellow, with results read directly off the printed scale calibrated for one pump stroke. With a TLV-TWA of 0.05–0.20 ppm and a 2-year shelf life, it's a reliable choice for monitoring ozone across a range of typical exposure levels.\u003c\/p\u003e\n\u003cp dir=\"auto\" class=\"font-claude-response-body break-words whitespace-normal\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/Ozone_Tube_No._NX200M_Data_Sheet.pdf?v=1784569700\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eData Sheet (PDF)\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Sampling Depot","offers":[{"title":"Default Title","offer_id":50363201224956,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX200M-Tube-box-Combo-2024-no-tube_1.png?v=1771746211","url":"https:\/\/samplingdepot.com\/products\/ozone-detector-tube-nx200m","provider":"Sampling Depot","version":"1.0","type":"link"}
