Ko te thermocouple he pūoko mo te ine i te pāmahana. E rua nga konganuku rereke e honoa ana ki tetahi pito. He maha nga momo thermocouples, momo J, K, T, & E nga momo tino noa (Base Metal), me te momo R, S, me B thermocouples e whakamahia ana i roto i nga tono pāmahana teitei (Nobal Metal).

He aha te waea toronga thermocouple?
Ka whakamahia te waea toronga Thermocouple ki te toro atu mai i te rangahau thermocouple ki te punaha whakahaere, whakaaturanga matihiko ranei inaa ko te waahi tawhiti. He iti ake te utu, he iti ake te karaehe i te waea thermocouple.
