Momo Wāhanga Whakawera Momo K Alumel /Tokotoko Chromer/ Rākau / Pae 6mm 8mm 9mm 10mm 12mm
Ko te momo K (CHROMEL vs ALUMEL) e whakamahia ana i roto i ngā hau whakahāngai, kore mahi, whakaiti maroke rānei. Me tiaki mai i ngā hau whanariki me ngā hau whakahāngai pakupaku. He pono, ā, he tino tika i ngā pāmahana teitei.

0.5″ 12.7mm KP Chromel KN Alumel Thermocouple Momo K Taupānga Tokotoko
Ko te āhuatanga o te Momo K he kaha tōna mahi ārai-waikura, ā, me whakamahi tonu i roto i te hau waikura me te hau kore mahi. Ko te pāmahana whakamahinga mō te wā roa ko te 1000℃, ā, ko te pāmahana whakamahinga mō te wā poto ko te 1200℃. Koinei te mea e whakamahia whānuitia ana i roto i ngā thermocouples katoa; (kāore e taea te whakamahi hei whakaiti i te hau hau).
