O le Universal hardness tester o se meafaigaluega su'esu'e atoatoa e fa'avae i luga ole ISO ma le ASTM fa'ata'ita'iga, e fa'ataga ai tagata fa'aoga e fa'atino su'ega ma'a'a Rockwell, Vickers ma Brinell i le meafaigaluega lava e tasi.O le Universal hardness tester e faʻataʻitaʻiina e faʻavae i luga o Rockwell, Brinell, ma Vickers mataupu faavae nai lo le faʻaogaina o le faʻaliliuga sootaga o le faiga maʻaʻa e maua mai ai le tele o tulaga faigata.
Ole fua ole malosi ole HB Brinell e fetaui lelei mo le fuaina o le maaa o le u'amea lafo, u'amea e le o ni u'amea, ma u'amea fa'afefete ma fa'afefe.E le talafeagai mo le fuaina o faʻataʻitaʻiga poʻo mea faigaluega e faigata tele, laʻititi tele, manifinifi tele, ma e le faʻatagaina ni faʻailoga tetele i luga.
Ole fua ole malosi ole HR Rockwell e talafeagai mo: su'ega fa'ailoga, fuaina maaa o vaega tineia, tineia ma fa'afefe vevela.
HV Vickers faigata fua e talafeagai mo: fuaina o le maaa o faʻataʻitaʻiga ma vaega faʻatasi ma vaega laiti ma tulaga maualuga maaa, o le maaa o infiltrated layers po o coatings pe a uma togafitiga eseese luga, ma le maaa o mea manifinifi.
O lo'o mulimuli mai ose fa'atomuaga i le fa'asologa fou o Universal hardness testers: ma le pa'i pa'i Universal Hardness Tester
E ese mai le masani masani Universal hardness tester, o le tupulaga fou Universal hardness tester e fa'aogaina le fa'aogaina o tekinolosi fa'amalosi ma le fa'aogaina o le fa'aogaina o le fa'aogaina e sui ai le fa'ata'ita'iga o le mamafa, fa'afaigofie le fua ma fa'amautu le tau.
