Universal hardness tester ha e le hantle ke sesebelisoa sa tlhahlobo se felletseng se ipapisitseng le litekanyetso tsa ISO le ASTM, se lumellang basebelisi ho etsa liteko tsa ho thatafala tsa Rockwell, Vickers le Brinell sesebelisoa se le seng.The Universal hardness tester e lekoa ho latela melao-motheo ea Rockwell, Brinell, le Vickers ho e-na le ho sebelisa kamano ea phetoho ea mokhoa oa ho thatafala ho fumana litekanyetso tse ngata tsa thatafalo.
Sekala sa boima ba HB Brinell se loketse ho metha ho thatafala ha tšepe e entsoeng ka tšepe, li-alloys tse se nang ferrous, le litšepe tse fapa-fapaneng tse halefileng le tse futhumetseng.Ha e loketse ho lekanya lisampole kapa li-workpieces tse thata haholo, tse nyane haholo, tse tšesaane haholo, 'me ha li lumelle li-indent tse kholo holim'a metsi.
Sekala sa boima ba HR Rockwell se loketse: hlobo ea liteko, tekanyo ea boima ba likarolo tse tingoeng, tse tingoeng le tse futhumetseng.
HV Vickers hardness scale e loketse: ho lekanya boima ba lisampole le likarolo tse nang le libaka tse nyenyane le boleng bo phahameng ba ho thatafala, ho thatafala ha lihlopha tse kentsoeng kapa liphahlo ka mor'a mekhoa e fapaneng ea phekolo ea holim'a metsi, le ho thatafala ha lisebelisoa tse tšesaane.
Se latelang ke selelekela sa letoto le lecha la liteko tsa boima ba Universal: le sekirini sa Universal Hardness Tester.
Ho fapana le mokhoa o tloaelehileng oa Universal hardness tester, moloko o mocha oa Universal hardness tester o sebelisa theknoloji ea sensor ea matla le mokhoa oa ho fana ka maikutlo a koaletsoeng ho nka sebaka sa mohlala oa boima ba 'mele, ho etsa hore tekanyo e be bonolo le boleng bo lekantsoeng bo tsitsitse haholoanyane.
