I-Universal hardness tester ngokwenene sisixhobo esibanzi sokuvavanya ngokusekelwe kwimigangatho ye-ISO kunye ne-ASTM, evumela abasebenzisi ukuba baqhube i-Rockwell, i-Vickers kunye ne-Brinell iimvavanyo zobulukhuni kwisixhobo esifanayo.Umvavanyi wobulukhuni be-Universal uvavanywa ngokusekelwe kwimigaqo ye-Rockwell, i-Brinell, kunye ne-Vickers kunokusebenzisa ubudlelwane bokuguqulwa kwenkqubo yobunzima ukufumana amaxabiso amaninzi obunzima.
Isikali sobulukhuni be-HB Brinell sikulungele ukulinganisa ubulukhuni bentsimbi etyhidiweyo, ii-alloys ezingenayo i-ferrous, kunye neentsimbi ezahlukeneyo ezifakwe emanzini kunye nezipholileyo.Ayifanelekanga ukulinganisa iisampulu okanye izixhobo zokusebenza ezinzima kakhulu, ezincinci kakhulu, ezincinci kakhulu, kwaye azivumeli ukujongwa okukhulu kumphezulu.
Isikali sobulukhuni se-HR Rockwell sifanelekile: ukungunda ukuvavanya, ukulinganisa ubulukhuni beendawo ezicinyiweyo, ezicinyiweyo kunye nobushushu obuphakathi.
Isikali sobulukhuni be-HV Vickers sifanelekile: ukulinganisa ubulukhuni beesampulu kunye neenxalenye ezineendawo ezincinci kunye namaxabiso aphezulu obunzima, ukuqina kweeleyile ezifakwe ngaphakathi okanye iingubo emva konyango oluhlukeneyo lomphezulu, kunye nobunzima bezinto ezincinci.
Oku kulandelayo sintshayelelo kuthotho olutsha lwabavavanyi bobulukhuni be-Universal: kunye nesikrini sokuchukumisa i-Universal Hardness Tester.
Ukwahluke kumvavanyi wobulukhuni bendalo yonke, isizukulwana esitsha somvavanyi wobulukhuni bendalo yonke sisebenzisa itekhnoloji ye-sensor yamandla kunye nenkqubo yempendulo ye-loop-loop evaliweyo ukuze ithathe indawo yemodeli yokulayisha ubunzima, ukwenza umlinganiso ube lula kwaye ixabiso elilinganisiweyo lizinze ngakumbi.
