A ceramic ball and the weight stack float on a thin film of air inside the nozzle, so the generated pressure is essentially free of friction, and the flow regulator holds the ball at float without operator input.\u003c\/p\u003e\n\u003cp\u003eThe Ametek PK2-404WC-SS-1B\/C Pneumatic Deadweight Tester combines the -1B accuracy grade with the \/C suffix: the certificate includes effective area, nominal pressure and actual pressure data. The 404WC is one of the two small-case PK II water-column models, with a 4 inH₂O weight carrier and ball output.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFloating-ball pneumatic design, virtually frictionless\u003c\/li\u003e\n\u003cli\u003e4 to 404 inH₂O certified range in 1 inH₂O steps\u003c\/li\u003e\n\u003cli\u003e±0.025% of reading accuracy (-1B grade)\u003c\/li\u003e\n\u003cli\u003eCertificate with effective area and pressure data (\/C)\u003c\/li\u003e\n\u003cli\u003eRugged ceramic measuring ball\u003c\/li\u003e\n\u003cli\u003eSelf-regulating flow control, no valve adjustment\u003c\/li\u003e\n\u003cli\u003eClosed-cover operation for outdoor use\u003c\/li\u003e\n\u003cli\u003eSmall case for bench or portable use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCalibration of low-pressure gauges and transmitters\u003c\/li\u003e\n\u003cli\u003eDraft and duct pressure instrument checks\u003c\/li\u003e\n\u003cli\u003eWater-column instrument calibration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTester base with case\u003c\/li\u003e\n\u003cli\u003eStainless steel weight set\u003c\/li\u003e\n\u003cli\u003eTubing kit\u003c\/li\u003e\n\u003cli\u003eInstruction manual\u003c\/li\u003e\n\u003cli\u003eNIST-traceable certificate of calibration with data\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAmetek PK2-404WC-SS-1B\/C Pneumatic Deadweight Tester Technical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eCertified range\u003c\/th\u003e\n\u003ctd\u003e4 to 404 inH₂O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIncrement\u003c\/th\u003e\n\u003ctd\u003e1 inH₂O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight carrier \/ ball output\u003c\/th\u003e\n\u003ctd\u003e4 inH₂O\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy\u003c\/th\u003e\n\u003ctd\u003e±0.025% of reading (-1B)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCertificate\u003c\/th\u003e\n\u003ctd\u003e\/C: effective area, nominal and actual pressure data\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 per °C outside 23°C\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 100 psi (206 to 689 kPa)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnection\u003c\/th\u003e\n\u003ctd\u003e1\/4 in female NPT with 1\/4 in tube adapter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBall\u003c\/th\u003e\n\u003ctd\u003eCeramic\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 on request\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCase\u003c\/th\u003e\n\u003ctd\u003eSmall case, 15 × 10.5 × 7 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003eUp to 28 lb (12.7 kg)\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\/products\/pressure\/deadweight-testers\/pk-ii-pneumatic-deadweight-tester\" target=\"_blank\" rel=\"noopener\"\u003ePK II on ametekcalibration.com\u003c\/a\u003e.\u003c\/p\u003e","brand":"Ametek","offers":[{"title":"Default Title","offer_id":67777010696379,"sku":"IMM_59195742","price":5736.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/ametek-mg-9.jpg?v=1792556054","url":"https:\/\/na.indomultimeter.net\/products\/ametek-pk2-404wc-ss-1b-c-pneumatic-deadweight-tester-4-to-404-inh2o","provider":"Indo Multimeter","version":"1.0","type":"link"}
