Break both tips off the tube, fit it to a Gastec GV-100 or GV-110 hand pump and draw the number of pump strokes listed for the expected range. The reagent changes from white to pale brown \/ pale green (dual layers), and the stain shows the gas concentration. Read the concentration directly on the scale printed on the tube. 10 tubes per box give 10 tests.\u003c\/p\u003e\u003cp\u003eCarbon monoxide comes from engines, generators, heaters and welding or burning work in enclosed or poorly ventilated areas. A tube gives a spot reading and does not replace a certified gas monitor where your site procedure requires one. Use only Gastec tubes with a Gastec pump, break the tips away from your eyes, and never handle broken glass or reagent with bare hands.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eMeasures carbon monoxide (CO) from 5 to 600 ppm\u003c\/li\u003e\u003cli\u003eColour change white to pale brown \/ pale green (dual layers)\u003c\/li\u003e\u003cli\u003eDirect-reading scale printed on the tube\u003c\/li\u003e\u003cli\u003eFor use with a Gastec GV-100 or GV-110 hand pump\u003c\/li\u003e\u003cli\u003e10 tubes per box, 36-month shelf life\u003c\/li\u003e\u003cli\u003eEach production lot is tested and calibrated by the manufacturer\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\u003ctr\u003e\u003cth\u003eBrand\u003c\/th\u003e\u003ctd\u003eGastec\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eManufacturer part number (MPN)\u003c\/th\u003e\u003ctd\u003e1LK\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eBig Papa SKU\u003c\/th\u003e\u003ctd\u003eBP-L-IG1LK\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eType\u003c\/th\u003e\u003ctd\u003eColourimetric detector tube\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eGas measured\u003c\/th\u003e\u003ctd\u003ecarbon monoxide (CO)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eMeasuring range\u003c\/th\u003e\u003ctd\u003e5–600 ppm\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003ePump strokes and sampling time\u003c\/th\u003e\u003ctd\u003e5–100 ppm: 3 strokes (300 mL) in 6 min; 100–300 ppm: 1 stroke (100 mL) in 2 min; 300–600 ppm: ½ stroke (50 mL) in 1 min\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eColour change\u003c\/th\u003e\u003ctd\u003ewhite to pale brown \/ pale green (dual layers)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eDetection limit\u003c\/th\u003e\u003ctd\u003e0.5 ppm (3 strokes)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eOperating temperature\u003c\/th\u003e\u003ctd\u003e0 to 40 °C (32 to 104 °F)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eRelative humidity\u003c\/th\u003e\u003ctd\u003e0 to 90 %\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eTemperature correction\u003c\/th\u003e\u003ctd\u003eNot required\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eTubes per box\u003c\/th\u003e\u003ctd\u003e10\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eShelf life\u003c\/th\u003e\u003ctd\u003e36 months\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eModel No.\u003c\/th\u003e\u003ctd\u003e1LK\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eDisposal note\u003c\/th\u003e\u003ctd\u003econtains 0.51 mg of selenium and 2.60 mg of hexavalent chromium per the SDS; dispose of per local regulations\u003c\/td\u003e\u003c\/tr\u003e\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eDocuments\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.gastec.co.jp\/files\/user\/asset\/pdf\/en\/sds\/1LK.pdf\" target=\"_blank\" rel=\"noopener\"\u003eSafety Data Sheet (SDS)\u003c\/a\u003e\u003c\/li\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.gastec.co.jp\/files\/user\/asset\/pdf\/en\/detector_tube\/1LK.pdf\" target=\"_blank\" rel=\"noopener\"\u003eSpecification sheet\u003c\/a\u003e\u003c\/li\u003e\u003cli\u003e\u003ca href=\"https:\/\/www.gastec.co.jp\/files\/user\/asset\/pdf\/en\/instructionmanual\/en\/1LK.pdf\" target=\"_blank\" rel=\"noopener\"\u003eUser instructions\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Gastec","offers":[{"title":"Default Title","offer_id":67568122855638,"sku":"BP-L-IG1LK","price":70000.0,"currency_code":"XOF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/8595\/3494\/files\/1lk.jpg?v=1791600573","url":"https:\/\/bigpapaentreprise.com\/en-sn\/products\/gastec-co-detector-tube-no-1lk-5-600-ppm-box-of-10-1lk","provider":"Big Papa Enterprise Ltd","version":"1.0","type":"link"}
