Fe/CuNi Type J Uea Huahana Thermocouple Alloy Bare Uea
Hōʻike huahana
ʻO Fe/CuNi Type J Thermocouple Alloy ʻAʻole Uea
Hōʻike huahana
Hoʻohana pinepine ʻia ka Thermocouple Type J no kāna kumu kūʻai haʻahaʻa a me ka EMF kiʻekiʻe Hiki ke hoʻohana ʻia i nā kūlana oxidizing a hiki i 760 ° C. No nā mahana kiʻekiʻe, pono e hoʻohana i nā anawaena uea nui.
He kūpono ke ʻano J thermocouple no ka hoʻoheheʻe ʻana, hoʻemi ʻana i ka ea inert a i ʻole ka ʻūhā.
