Tuatahi, mō te hanganga rauemi, ko te waea thermocouple momo-J he mea hanga mai i te huinga rino-pūmau. Ko te rino te waewae pai, ko te pūmau (hekoranu parahi-nikara) hei waewae kino. He rerekē, ko te waea thermocouple momo-K he mea hanga ki tekōromere- te huinga alumera. Ko te kromera, he mea hanga nui ki te nikara me te konupora, te waewae pai, ā, ko te alumera, he koranu nikara-konumohe-mangasin-silicon, te waewae kino. Nā tēnei rerekētanga o te rauemi ka rerekē ngā āhuatanga o ā rātou mahi.

Tuarua, he rerekē rawa ngā awhe pāmahana ka taea e rātou te ine.Ngā takirua wera momo-JKa taea te ine i ngā pāmahana mai i te -210°C ki te 760°C. He pai mō ngā momo tono me ngā whakaritenga pāmahana taurite. Hei tauira, i roto i te umanga tukatuka kai, ka whakamahia ngā takirua wera momo-J i roto i ngā oumu tunu. I te tunu taro, ko te pāmahana i roto i te oumu mai i te 150°C ki te 250°C. Ka taea e ā mātou waea takirua wera momo-J kounga teitei te aroturuki tika i ēnei pāmahana, kia rite ai te tunu o te taro, kia tino tika ai te kakano. Ko tētahi atu tono kei roto i te hanga rongoā, e whakamahia ana ngā takirua wera momo-J hei ine i te pāmahana i te wā e whakamaroke ana i ētahi rongoā. He maha ngā wā ka puritia te pāmahana i roto i tēnei tukanga i roto i te 50°C ki te 70°C, ā, ka taea e ā mātou hua waea takirua wera momo-J te whakarato raraunga pāmahana pono, hei tiaki i te kounga o ngā rongoā.

Ko ngā thermocouples momo-K ia, he whānui ake te awhe pāmahana, mai i te -200°C ki te 1350°C. Nā tēnei ka tino hiahiatia rātou i roto i ngā tono pāmahana teitei. I roto i te umanga hanga maitai,Ngā takirua wera momo-Ke whakamahia ana hei aroturuki i te pāmahana i roto i te oumu pupuhi. Ka taea e ngā pāmahana i roto i te oumu pupuhi te eke ki te 1200°C, neke atu rānei. Ka taea e ā mātou waea thermocouple momo-K te tu atu i taua wera nui me te pupuri tonu i te tika teitei, e āhei ai ngā kaiwhakahaere ki te whakahaere tika i te tukanga whakarewa me te whakarite i te kounga o te maitai. I roto i te mara o te rererangi, i te wā e whakamātautau ana i ngā wāhanga miihini jet, ka whakamahia ngā thermocouple momo-K hei ine i ngā hau pāmahana teitei i hangaia i te wā e mahi ana te miihini. Ka taea e ēnei hau te eke ki ngā pāmahana tata ki te 1300°C, ā, ka taea e ā mātou hua waea thermocouple momo-K te whakarato i ngā pānui pāmahana tika, he mea nui mō te whakawhanake me te arotau i ngā miihini jet.

Ko te tika tētahi atu āhuatanga matua. Ko ngā thermocouple momo-K he pai ake te tika i runga i te whānuitanga o te pāmahana ki te whakaritea ki ngā thermocouple momo-J. Ko te pumau o ngā thermocouple momo-K i roto i ngā taiao uaua ka whai wāhi atu ki tō rātou tika teitei ake, ka waiho hei whiringa pai mō ngā rangahau pūtaiao me ngā tukanga ahumahi tino tika.

I Tankii, ka hangaia ā mātou hua waea whakamahana J me K me te mana whakahaere kounga tino pakari. Ka whakarite ā mātou waea whakamahana momo-J i te mahi pono i roto i te awhe pāmahana kua tohua, ko ā mātou waea whakamahana momo-K he mea hanga kia tu atu ki ngā pāmahana teitei me te tino tika me te pumau. Ahakoa me ine koe i ngā tukanga whakamatao pāmahana iti, i ngā tauhohenga ahumahi pāmahana teitei rānei, ka taea e ā mātou hua waea whakamahana te whakarato ki a koe i ngā raraunga pāmahana tika me te pumau, hei āwhina i a koe ki te arotau i ō mahi me te whakarite i te kounga o te hua.
