{"product_id":"gastec-hydrogen-detector-tube-no-30-0-5-2-box-of-10-30","title":"Gastec Hydrogen Detector Tube No. 30, 0.5–2 %, Box of 10","description":"\u003cp\u003eGastec detector tube No. 30 measures hydrogen (H2) in air from 0.5 to 2 %. 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 yellow to yellowish brown, and the stain shows the gas concentration. This is not a direct-reading tube: read the stain length against the concentration chart supplied with the tube. 10 tubes per box give 10 tests.\u003c\/p\u003e\u003cp\u003eHydrogen can collect near battery rooms, charging areas, electrolysis units and process lines. 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 hydrogen (H2) from 0.5 to 2 %\u003c\/li\u003e\u003cli\u003eColour change yellow to yellowish brown\u003c\/li\u003e\u003cli\u003eConcentration chart supplied with 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\u003e30\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eBig Papa SKU\u003c\/th\u003e\u003ctd\u003eBP-L-IG30\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\u003ehydrogen (H2)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eMeasuring range\u003c\/th\u003e\u003ctd\u003e0.5–2 %\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003ePump strokes and sampling time\u003c\/th\u003e\u003ctd\u003e0.5–2 %: 1 stroke (100 mL) in 3 min\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eColour change\u003c\/th\u003e\u003ctd\u003eyellow to yellowish brown\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eDetection limit\u003c\/th\u003e\u003ctd\u003e0.5 % (1 stroke)\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\u003e30\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\/30.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\/30.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\/30.pdf\" target=\"_blank\" rel=\"noopener\"\u003eUser instructions\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Gastec","offers":[{"title":"Default Title","offer_id":67568125608150,"sku":"BP-L-IG30","price":152.18,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/8595\/3494\/files\/30.jpg?v=1791600785","url":"https:\/\/bigpapaentreprise.com\/en-ca\/products\/gastec-hydrogen-detector-tube-no-30-0-5-2-box-of-10-30","provider":"Big Papa Enterprise Ltd","version":"1.0","type":"link"}
