This tube reacts with sulfur dioxide to shift from yellow to blue, with results read directly off the printed scale calibrated for one pump stroke. With a TLV-STEL of 0.25 ppm and a 3-year shelf life, it's well-suited for monitoring elevated sulfur dioxide levels in industrial applications.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"auto\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/Sulfur_Dioxide_Tube_No._NX211H_Data_Sheet.pdf?v=1784570375\" 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":50363226030332,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX211H-tube-box-2024_combo.jpg?v=1771746204","url":"https:\/\/samplingdepot.com\/products\/sulfur-dioxide-detector-tube-nx211h","provider":"Sampling Depot","version":"1.0","type":"link"}
