Mefuta e mengata ea Likopo
Li-heater tsa rod ea silicon carbide li sebetsa haholo masimong a mangata, li loketse:
- Ho qhibilihisa letsopa le ho qhibiliha ha khalase
- Ts'ebetso ea tšepe
- Tlhahiso ea thepa e halefisang
- Lifono tsa motlakase tsa laboratori
- Likarabelo tsa lik'hemik'hale tse nang le mocheso o phahameng
