Tirohanga Whānui mō te Wāhanga 1
Ko ngā takirua wera platinum-iridium 10-platinum paerewa tuatahi me te tuarua he tino tika, he pai ngā āhuatanga ā-tinana me te matū, he pai te ātete ki te waikura i ngā pāmahana teitei, he pai te pumau me te kaha ki te whakaputa anō i te kaha hikohiko wera. Nō reira, e whakamahia ana hei taputapu ine paerewa i roto i te (419.527~1084.62) °C, e whakamahia ana hoki hei tuku i te nui o te pāmahana me te ine tika i te pāmahana i roto i te awhe pāmahana.

| Ringaringa whakamātao | Ngongo porcelain rua-kōhao, ngongo korundum rānei. Diameter o waho (3~4)mm, diameter kōhao (0.8~1.0)mm, roa (500~550)mm | |
Me rite ngā takirua wera platinum-iridium 10-platinum paerewa ki te ripanga pūnaha tuku ā-motu, me whakatinana ngā tikanga manatoko ā-motu. Ka taea te whakamahi i ngā takirua wera platinum-iridium 10-platinum paerewa taumata tuatahi hei ine i ngā takirua wera platinum-iridium 10-platinum taumata tuarua, taumata I, taumata II me ngā takirua wera whakarewa turanga taumata I; ka taea anake te whakamahi i ngā takirua wera platinum-iridium 10-platinum taumata tuarua hei ine i ngā takirua wera whakarewa turanga taumata I.

Wāhanga 4 Te tiaki me te tiaki
1. Ko te roanga o te whakatikatika i te takirua wera paerewa he 1 tau, ā, i ia tau me whakatikatika te takirua wera paerewa e te tari ine ine.
2. Me whakahaere te whakatikatika tirotiro e tika ana kia rite ki te whakamahinga.
3. Me ma te taiao mahi o te thermocouple paerewa kia kore ai e poke te thermocouple paerewa.
4. Me whakanoho te thermocouple paerewa ki tētahi āhua kore-parahanga, ā, me tiaki hoki i te ahotea ā-ringa.
Wāhanga 5 Ngā Whakatūpato ina whakamahia
1. Kāore e taea te whakamahi i te ngongo whakamahana i te tunu wera nui. Ka whakamahia te ngongo whakamahana taketake i muri i te horoinga tino tika me te tunu wera nui.
2. Kāore te ngongo whakamarumaru e aro ki te pai me te kino, ka poke te pou konukawata, ka heke hoki te uara pūmanawa hiko wera.
3. Ka poke matapōkeretia te takirua wera paerewa e te ngongo whakamahana wera paerewa me te waea iti te utu, ā, me whakamahi te ngongo whakarewa tiaki hei manatoko i te takirua whakarewa turanga.
4. Kāore e taea te whakanoho ohorere i te takirua wera paerewa ki roto i te oumu whakahaere pāmahana, kāore hoki e taea te tango mai i te oumu whakahaere pāmahana. Ka pā te wera me te makariri ohorere ki te mahi hiko wera.
5. I raro i ngā āhuatanga noa, me wehewehe rawa te oumu manatoko mō te thermocouple konganuku utu nui me te thermocouple konganuku turanga; ki te kore e taea, me whakauru te ngongo uku ma, te ngongo korundum rānei (te diameter tata ki te 15mm) ki te ngongo oumu hei tiaki i ngā thermocouple konganuku utu nui me ngā thermocouple paerewa mai i te parahanga o te thermocouple konganuku turanga.
