電(dian)熱(re)(re)恒(heng)溫鼓風干(gan)燥箱又叫烤箱或烘箱。主(zhu)要由箱體(ti)、電(dian)熱(re)(re)器(qi)和溫度(du)(du)控制系統三部分組成，近年生產(chan)的干(gan)燥箱在(zai)此基礎上增加了(le)了(le)溫度(du)(du)顯示器(qi)及溫度(du)(du)設置器(qi)。

電(dian)熱(re)(re)(re)恒(heng)(heng)溫(wen)鼓(gu)風干(gan)(gan)燥(zao)箱用(yong)(yong)于(yu)(yu)干(gan)(gan)燥(zao)物(wu)(wu)品或干(gan)(gan)熱(re)(re)(re)滅微生(sheng)物(wu)(wu)。其(qi)恒(heng)(heng)溫(wen)調(diao)節(jie)范圍(wei)(wei)，（50～200）℃（或（50～250）℃、（50～300）0C）；培(pei)養箱用(yong)(yong)于(yu)(yu)培(pei)養微生(sheng)物(wu)(wu)等。其(qi)恒(heng)(heng)溫(wen)調(diao)節(jie)范圍(wei)(wei)：自(zi)高于(yu)(yu)室溫(wen)起至(zhi)60℃；水溫(wen)箱用(yong)(yong)于(yu)(yu)間接恒(heng)(heng)溫(wen)加熱(re)(re)(re)。其(qi)恒(heng)(heng)溫(wen)調(diao)節(jie)范圍(wei)(wei)；自(zi)高于(yu)(yu)室溫(wen)起至(zhi)65℃。上述(shu)三種箱體(ti)都是采用(yong)(yong)電(dian)來(lai)加熱(re)(re)(re)的，有(you)時又將它們統稱為電(dian)熱(re)(re)(re)箱。
