Certified range models run from 1 to 51 psi (RK-50) up to 1 to 2011 kPa (RK-2000N), with pressure range 0.145 to 300 psi (1 to 2000 kPa) overall, so gauges and transmitters can be calibrated against a directly traceable force balance rather than a secondary reference.\u003c\/p\u003e\n\u003cp\u003eThree accuracy grades are available: ±(0.05% of reading) as standard, ±(0.025% of reading) with the -1B suffix, and ±(0.015% of reading) with the -1A suffix, with repeatability ±0.005% of reading. Weights are stainless steel as standard, the ball is ceramic, the connection is 1\/8 in female NPT, and standard delivery includes the tester base with case, weight set, manual and NIST-traceable certificate. Water-column models reference 20°C (ISA) or 60°F (AGA) and gravity is set to the international standard 9.80655 m\/s² unless local gravity is specified.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAccuracy options: ±0.05%, ±0.025% or ±0.015% of reading\u003c\/li\u003e\n\u003cli\u003eRepeatability ±0.005% of reading\u003c\/li\u003e\n\u003cli\u003ePressure range 0.145 to 300 psi \/ 1 to 2000 kPa across models\u003c\/li\u003e\n\u003cli\u003eCeramic ball with stainless steel weight masses\u003c\/li\u003e\n\u003cli\u003eOperates on nitrogen or instrument\/shop air, 30 to 450 psi supply\u003c\/li\u003e\n\u003cli\u003eReadings in psi, kg\/cm², bar, kPa, inH2O, cmH2O and inHg\u003c\/li\u003e\n\u003cli\u003eNIST-traceable certificate included as standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePrimary-standard calibration of pressure gauges and transmitters\u003c\/li\u003e\n\u003cli\u003eBenchmark for digital pressure calibrators in metrology labs\u003c\/li\u003e\n\u003cli\u003eShop and field verification of low-pressure pneumatic instruments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAmetek RK Pneumatic Deadweight Tester Technical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy\u003c\/th\u003e\n\u003ctd\u003e±(0.05% of reading) standard; ±0.025% (-1B); ±0.015% (-1A)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRepeatability\u003c\/th\u003e\n\u003ctd\u003e±0.005% of reading\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTemperature coefficient\u003c\/th\u003e\n\u003ctd\u003e±0.00167% of reading\/°C outside 23°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePressure range\u003c\/th\u003e\n\u003ctd\u003e0.145 to 300 psi \/ 1 to 2000 kPa (family)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGravity reference\u003c\/th\u003e\n\u003ctd\u003e9.80655 m\/s² international standard; local gravity on request\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWater column reference\u003c\/th\u003e\n\u003ctd\u003e20°C ISA standard; 60°F AGA standard when specified\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePressure source\u003c\/th\u003e\n\u003ctd\u003eNitrogen or instrument\/shop air\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupply pressure\u003c\/th\u003e\n\u003ctd\u003e30 to 450 psi (210 to 3,100 kPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutput flow\u003c\/th\u003e\n\u003ctd\u003e1 scfh at 0.15 psi to 60 scfh at 300 psi\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnection\u003c\/th\u003e\n\u003ctd\u003e1\/8 in female NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBall \/ masses\u003c\/th\u003e\n\u003ctd\u003eCeramic ball; stainless steel masses (aluminum small increments optional)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTester enclosure\u003c\/th\u003e\n\u003ctd\u003e15 × 9 × 8 in; 18 to 31.5 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeights case\u003c\/th\u003e\n\u003ctd\u003e12 × 8.5 × 11.5 in; masses 17.5 to 61.5 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStandard delivery\u003c\/th\u003e\n\u003ctd\u003eTester base with case, weight set, manual, NIST-traceable certificate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003eManufacturer information: \u003ca href=\"https:\/\/www.ametekcalibration.com\/-\/media\/ametekcalibration\/download_links\/pressure\/deadweight-testers\/deadweight-tester-rk-data-sheet-us.pdf\" target=\"_blank\" rel=\"noopener\"\u003eRK deadweight tester datasheet on ametekcalibration.com\u003c\/a\u003e.\u003c\/p\u003e","brand":"Ametek","offers":[{"title":"Default Title","offer_id":67776200671419,"sku":"IMM_86575493","price":5251.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/ametek-mg-rk.jpg?v=1792552103","url":"https:\/\/na.indomultimeter.net\/products\/ametek-rk-pneumatic-deadweight-tester-0-145-to-300-psi-0-05-of-reading","provider":"Indo Multimeter","version":"1.0","type":"link"}
