Thermocouple Type K Alumel / Chromel Rod / La'au / Pa 6mm 8mm 9mm 10mm 12mm
Thermocouple Type K Alumel /O'au o Chromel/ Laau / Pa 6mm 8mm 9mm 10mm 12mm
TUSI K (CHROMEL vs ALUMEL) e faʻaaogaina i le faʻamaʻiina, faʻamago poʻo le faʻamamago faʻaitiitia atemosifia. E tatau ona puipuia mai le sulfurous ma fa'ama'i fa'ama'i fa'asao. E faʻatuatuaina ma e maualuga le saʻo i le maualuga o le vevela.

O le uiga o le Ituaiga K o loʻo i ai le malosi o le anti-oxidation performance, ma e tatau ona faʻaaogaina faʻaauau i totonu o se siosiomaga faʻamaʻi ma le inert. Ole vevela ole fa'aoga umi ole 1000 ℃ ma le taimi pupuu 1200 ℃. E sili ona fa'aaogaina i totonu o thermocouple uma; (e le mafai ona faʻaaogaina e faʻaitiitia ai le siosiomaga kesi).
