{"product_id":"manometro-con-aguja","title":"Pressure gauge with needle","description":"\u003cp\u003eVerifying the integrity of every meter of seam in installed geomembrane to certify the watertightness of a dam, landfill, or leaching cell under environmental standards requires a needle pressure gauge with a metal body, clear dial reading, and robust construction for continuous field use. This needle pressure gauge —also called an \u003cstrong\u003eair pressure tester\u003c\/strong\u003e, weld channel tester, or air pressure gauge tester— is manufactured by KORWINS with a metal body, stainless steel needle, and ergonomic wooden handle, designed for geomembrane installation contractors, hydraulic works supervisors, and environmental quality control technicians.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustrial-grade metal body:\u003c\/strong\u003e robust construction sized for continuous field use, ambient humidity, quarry dust, and rough handling in sanitary landfills and mining, without losing calibration accuracy.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrecision stainless steel insertion needle:\u003c\/strong\u003e tip sized to penetrate cleanly into the air channel of the dual weld without compromising the material structure, a critical condition for non-destructive seam testing.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClear, accurate dial reading:\u003c\/strong\u003e visible scale that allows pressure monitoring throughout the test cycle and immediate detection of any pressure drop indicative of a leak, an auditable condition for project certification.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eErgonomic wooden handle:\u003c\/strong\u003e comfortable, firm grip that facilitates the manual force needed for needle insertion and handling during continuous testing cycles on long seams.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection hose with quick coupling:\u003c\/strong\u003e high visibility and direct connection to portable air pumps or manual compressors, a condition for autonomous field operation without complex pneumatic equipment.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTypical applications and uses\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eQuality control during geomembrane installation: verifying watertightness meter by meter on dual-seam welds.\u003c\/li\u003e\n  \u003cli\u003eEnvironmental auditing of sanitary landfills and leaching cells under ISO 14001 or equivalent certification.\u003c\/li\u003e\n  \u003cli\u003eVerification of waterproofing in dams, reservoirs, artificial lakes, and large-format agricultural water storage.\u003c\/li\u003e\n  \u003cli\u003eInspection of mining projects with leaching cells and chemical containment using structural HDPE or LLDPE.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eQuality and durability\u003c\/h3\u003e\n\u003cp\u003eAn economical field pressure gauge fails on two fronts: the initial calibration loses reliability after a few months of use (which produces false readings that invalidate later audits) and the insertion needle is made of low-grade steel that bends or rusts (which ruins the test on the first intensive use). KORWINS works with a calibrated metal body and a stainless steel needle, which separates a quality-control tester certifiable for auditing from a basic pressure gauge that certifies nothing.\u003c\/p\u003e\n\n\u003cdiv style=\"background-color: #F3F6F3; padding: clamp(14px, 4vw, 18px); margin-top: 20px; font-size: 0.9em; color: #555555; border-radius: 8px;\"\u003e\n  \u003cstrong style=\"color: #006902;\"\u003eAlso known as:\u003c\/strong\u003e\n  \u003cstrong\u003eTechnical:\u003c\/strong\u003e air pressure gauge tester, weld channel pressure tester, geomembrane watertightness tester, needle pressure test kit, dual seam pressure tester.\n  \u003cstrong\u003eIn DR and Caribbean:\u003c\/strong\u003e manómetro de aguja, probador de soldadura, manómetro para geomembrana, tester de costura.\n  \u003cstrong\u003eIn other countries:\u003c\/strong\u003e air pressure tester (USA), needle pressure gauge (USA), dual seam tester (USA), tester soldadura HDPE (LATAM), manómetro de aguja (LATAM, ES), probador de canal de aire (MX).\n\u003c\/div\u003e","brand":"KORWINS","offers":[{"title":"Standard","offer_id":52455861518664,"sku":"126342","price":57000.0,"currency_code":"DOP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0916\/9751\/2776\/files\/manometro-prueba-estanqueidad-geomembrana-rd.png?v=1771612888","url":"https:\/\/dodom.com\/en\/products\/pressure-gauge-with-needle","provider":"Dodom","version":"1.0","type":"link"}
