Muyedzo wehukukutu hweUniversal chaizvoizvo chishandiso chakakwana chekuyedza chakavakirwa pamiyero yeISO neASTM, zvichibvumira vashandisi kuita bvunzo dzehukukutu hweRockwell, Vickers naBrinell pachishandiso chimwe chete. Muyedzo wehukukutu hweUniversal unoyedzwa zvichibva pamisimboti yeRockwell, Brinell, naVickers pane kushandisa hukama hwekushandura hwehurongwa hwekukukutu kuti uwane hunhu hwakawanda hwekukukutu.
Chikero cheHB Brinell chekuomarara chakakodzera kuyera kuomarara kwesimbi yakakandwa, alloys dzisina ferrous, uye simbi dzakasiyana-siyana dzakanyoroveswa uye dzakapfava. Hazvina kukodzera kuyera sampuro kana workpieces dzakaoma zvakanyanya, diki zvakanyanya, dzakatetepa zvakanyanya, uye dzisingabvumire maburi makuru pamusoro.
Chikero chekuomarara cheHR Rockwell chakakodzera: kuyedza mapundu, kuyerwa kwekuomarara kwezvikamu zvakadzimwa, zvakadzimwa uye zvakapiswa nekupisa.
Chikero chekuomarara cheHV Vickers chakakodzera: kuyera kuomarara kwemasampuli nezvikamu zvine nzvimbo diki uye kuomarara kwakanyanya, kuomarara kwemachira akapinda kana machira mushure mekurapa kwakasiyana-siyana pamusoro, uye kuomarara kwezvinhu zvitete.
Zvinotevera ndezve sumo kune nhevedzano itsva yevaongorori vekusimbisa kuomarara kweUniversal: uye Universal Hardness Tester yekubata skrini
Kusiyana neUniversal hardy tester yechinyakare, Universal hardy tester yechizvarwa chitsva inoshandisa tekinoroji ye force sensor uye closed-loop force feedback system kutsiva weight-loading model, zvichiita kuti kuyerwa kuve nyore uye kukosha kwakayerwa kuve kwakasimba.
