Lautele Lalolagi Mea Faigata Tester / Uʻamea Faigata Faʻataʻitaʻi Masini
Faʻamatalaga:
1. O le maaa o se tasi taua uiga taua masini o mea ao le faigata tofotofoga o le sili ona vave ma le tamaoaiga suʻesuʻega metotia, faʻapea foi ma se taua auala e faʻamasino le lelei o le uamea mea poʻo ona vaega vaega. O le masini masini o le tele o uamea mea e pei o le malosi, lelava, wriggling ma ofuina i fafo mafai ona tofotofoina faʻatatau e ala i lona faigata tofotofoga.
2. O leotor Brinell Rockwell & Vickers Hardness Tester, o le tele-functional hardness tester ma Brinell, Rockwell & Vickers 3 ituaiga o metotia faʻataʻitaʻi ma 7 sitepu faʻamalosi malosi o le a faʻamalieina manaʻoga o le tele o ituaiga o faigata fuaina. O le mea faigaluega ua faʻaaogaina otometi shifter e uta, nofo ma aveʻese le faʻataʻitaʻiga malosi, o le mea lea o le faʻagaioiga mo lenei mea faigaluega e faigofie, faigofie ma vave.
