Universal hardness tester yog qhov ntsuas ntsuas ntsuas raws li ISO thiab ASTM cov qauv, tso cai rau cov neeg siv ua Rockwell, Vickers thiab Brinell hardness tests ntawm tib lub ntsuas.Lub Universal hardness tester yog kuaj raws li Rockwell, Brinell, thiab Vickers cov hauv paus ntsiab lus es tsis yog siv kev hloov pauv kev sib raug zoo ntawm cov txheej txheem hardness kom tau txais ntau qhov tseem ceeb hardness.
HB Brinell hardness scale yog haum rau ntsuas qhov hardness ntawm cam khwb cia hlau, non-ferrous alloys, thiab ntau yam annealed thiab tempered steels.Nws tsis tsim nyog rau kev ntsuas cov qauv lossis cov khoom ua haujlwm uas nyuaj dhau, me me dhau, nyias dhau, thiab tsis txhob tso cov indentations loj rau ntawm qhov chaw.
HR Rockwell hardness scale yog tsim rau: kuaj pwm, hardness ntsuas ntawm quenched, quenched thiab tempered tshav kub kho qhov chaw.
HV Vickers hardness scale yog haum rau: ntsuas qhov hardness ntawm cov qauv thiab qhov chaw nrog me me thiab hardness qhov tseem ceeb, hardness ntawm infiltrated txheej los yog coatings tom qab ntau yam kev kho deg, thiab hardness ntawm nyias cov ntaub ntawv.
Cov hauv qab no yog kev taw qhia rau cov tshiab series ntawm Universal hardness testers: thiab kov screen Universal Hardness Tester
Sib txawv ntawm cov tsoos Universal hardness tester, lub cim tshiab Universal hardness tester siv lub zog sensor technology thiab kaw-voj quab yuam tawm tswv yim system los hloov cov qauv hnyav-loading, ua qhov kev ntsuas yooj yim thiab ntsuas tus nqi ruaj khov.
