Universal Mata Taonga Rawa Tester / Miihini Tohu Whakamatau Miihini
Whakaahuatanga:
1. Ko te pakeke tetahi o nga ahuatanga miihini nui o te rauemi ko te whakamatautau i te pakeke ko te tikanga whakamatautau tere rawa atu me te ohanga, me tetahi tikanga nui ki te whakawa i te kounga o nga rawa whakarewa o ona waahanga waahanga ranei. Ko nga ahuatanga miihini o te nuinga o nga taonga whakarewa penei i te kaha, ngenge, ngau kino me te whakakakahu ka taea te whakamatautau i roto i nga whakamatautau pakeke.
2. Ko te Kaiwhakaputa Brinell Rockwell & Vickers Hardness Tester, he kaiwhakaatu pakeke-mahi maha me Brinell, Rockwell & Vickers 3 momo momo tikanga whakamatautau me nga taahiraa e 7 nga nekehanga whakamana ka tutuki nga hiahia o nga momo inenga pakeke. He mea kawe noa te taputapu hei uta, hei noho, hei tango i te kaha whakamatautau, na reira he ngawari, he ngawari, he tere hoki te mahinga mo tenei taputapu.
