低(di)溫(wen)(wen)恒(heng)(heng)(heng)溫(wen)(wen)槽(cao)是(shi)我廠根據用(yong)戶要求(qiu)在恒(heng)(heng)(heng)溫(wen)(wen)水(shui)(shui)浴(yu)鍋基礎上改進而(er)來的(de)低(di)溫(wen)(wen)恒(heng)(heng)(heng)溫(wen)(wen)槽(cao)，改變了以往恒(heng)(heng)(heng)溫(wen)(wen)水(shui)(shui)浴(yu)鍋只有(you)(you)加(jia)熱功能而(er)不(bu)能制冷的(de)弊端(duan)，從而(er)使低(di)溫(wen)(wen)水(shui)(shui)浴(yu)鍋具有(you)(you)比普通恒(heng)(heng)(heng)溫(wen)(wen)水(shui)(shui)浴(yu)鍋具有(you)(you)更為廣泛(fan)的(de)控溫(wen)(wen)范圍，Z低(di)冷卻(que)溫(wen)(wen)度可至零下80℃，水(shui)(shui)箱內(nei)的(de)冷卻(que)液(ye)可以引出用(yong)以建立第二恒(heng)(heng)(heng)溫(wen)(wen)場(chang)，真正做到一機多用(yong)。
