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 yellow, 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\u003eMercaptans are the odorants added to natural gas and LP gas, and they are also released in refining and sour gas processing. 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 mercaptans (RSH) from 0.5 to 120 ppm\u003c\/li\u003e\u003cli\u003eColour change white to yellow\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\u003e70\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eBig Papa SKU\u003c\/th\u003e\u003ctd\u003eBP-L-IG70\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\u003emercaptans (RSH)\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eMeasuring range\u003c\/th\u003e\u003ctd\u003e0.5–120 ppm\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003ePump strokes and sampling time\u003c\/th\u003e\u003ctd\u003e0.5–5 ppm: 2 to 10 strokes (200–1000 mL) in 3 to 15 min; 5–120 ppm: 1 stroke (100 mL) in 1.5 min\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eColour change\u003c\/th\u003e\u003ctd\u003ewhite to yellow\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eDetection limit\u003c\/th\u003e\u003ctd\u003e0.2 ppm (10 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\u003eRequired (see the instruction manual)\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\u003e70\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003cth\u003eDisposal note\u003c\/th\u003e\u003ctd\u003econtains 0.91 mg of lead 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\/70.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\/70.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\/70.pdf\" target=\"_blank\" rel=\"noopener\"\u003eUser instructions\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Gastec","offers":[{"title":"Default Title","offer_id":67568125214934,"sku":"BP-L-IG70","price":109.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/8595\/3494\/files\/70.jpg?v=1791600733","url":"https:\/\/bigpapaentreprise.com\/en\/products\/gastec-mercaptan-detector-tube-no-70-0-5-120-ppm-box-of-10-70","provider":"Big Papa Enterprise Ltd","version":"1.0","type":"link"}
