Bayani: W707Ni wani lantarki ne na ƙarfe mai ƙarancin zafin jiki wanda ke ɗauke da Ni a cikin wani shafi mai ƙarancin hydrogen sodium. Yi amfani da DCEP (mai nuna wutar lantarki kai tsaye) kuma ana iya haɗa shi a kowane matsayi. Har yanzu ƙarfen da aka ajiye yana da ƙarfi mai kyau a -70°C.
Aikace-aikace: Ana amfani da shi don walda ƙarfe mai ƙarancin zafi kamar 2.5Ni.
