The Universal hardness tester kwenikweni ndi chida choyesera chathunthu chotengera miyezo ya ISO ndi ASTM, kulola ogwiritsa ntchito kuyesa kuuma kwa Rockwell, Vickers ndi Brinell pachida chomwecho.The Universal hardness tester imayesedwa potengera mfundo za Rockwell, Brinell, ndi Vickers m'malo mogwiritsa ntchito ubale wotembenuka wa hardness system kuti apeze mfundo zowuma zingapo.
Sikelo ya kuuma kwa HB Brinell ndiyoyenera kuyeza kuuma kwa chitsulo choponyedwa, ma aloyi osagwiritsa ntchito chitsulo, ndi zitsulo zosiyanasiyana zopindika komanso zowuma.Sikoyenera kuyeza zitsanzo kapena zida zogwirira ntchito zomwe zimakhala zolimba kwambiri, zazing'ono, zoonda kwambiri, ndipo sizimalola ma indentation akuluakulu pamtunda.
HR Rockwell kuuma sikelo ndiyoyenera: kuyesa nkhungu, kuyeza kuuma kwa magawo ozimitsidwa, kuzimitsidwa ndi kutentha kwapang'onopang'ono.
HV Vickers kuuma sikelo ndi yoyenera: kuyeza kuuma kwa zitsanzo ndi magawo omwe ali ndi madera ang'onoang'ono ndi kuuma kwakukulu, kuuma kwa zigawo zolowetsedwa kapena zokutira pambuyo pa mankhwala osiyanasiyana a pamwamba, ndi kuuma kwa zipangizo zoonda.
Zotsatirazi ndikuyambitsa mndandanda watsopano wa Universal hardness testers: ndi touch screen Universal Hardness Tester.
Mosiyana ndi Universal hardness tester, m'badwo watsopano wa Universal hardness tester umagwiritsa ntchito ukadaulo wa sensor sensor ndi njira yotsekera yamphamvu yotsekera kuti ilowe m'malo mwa chitsanzo chotsitsa zolemetsa, kupangitsa kuti kuyeza kukhale kosavuta komanso mtengo wake ukhale wolimba.
