ʻōniʻoniʻonā mea hoʻomehana uilai loko o ka cylindrical spirals i hana ʻia e hoʻokahi a ʻelua mau uwea kū'ē o ka alloy kūpono ma muli o ke noi.
ʻO kāna mau hiʻohiʻona nui ka hoʻopili ʻana i kahi mea hoʻomehana nickel-chrome alloy wire a me kahi ʻano hoʻohālikelike maʻamau o -230 V.
ʻO nā noi maʻamau: nā mea maloʻo ʻoihana, nā mea hoʻomehana ea, nā kapuahi, etc.
Eia kekahi, a e like me ka uea alloy i loko o lākou, hiki iā mākou ke hoʻokaʻawale i ʻekolu ʻano o nā hiʻohiʻona:

• Nā hiʻohiʻona M, me ka maikaʻi 20-5 a i manaʻo nui ʻia no nā kapuahi.
• Nā hiʻohiʻona MS, me ka maikaʻi 80-20 a pono no nā noi āpau.
• Nā hiʻohiʻona MC, me ka maikaʻi 20-5 a hoʻohana ʻia i nā paipu quartz a me infrared.
• Hōʻike huahana
