高低溫(wen)恒溫(wen)槽簡稱恒溫(wen)槽，常用于實驗室、科研(yan)場所，是(shi)一種可(ke)提供恒定(ding)溫(wen)度(du)的(de)槽體。廣泛用于生(sheng)物、化工(gong)、化學、制藥、生(sheng)命科學、物性(xing)測試等行業的(de)高等院校，企業質檢及生(sheng)產部門。

  高低(di)溫(wen)(wen)恒(heng)(heng)(heng)溫(wen)(wen)槽(cao)?之所(suo)以能夠恒(heng)(heng)(heng)溫(wen)(wen)主要是依靠恒(heng)(heng)(heng)溫(wen)(wen)控制(zhi)起來(lai)控制(zhi)恒(heng)(heng)(heng)溫(wen)(wen)槽(cao)的熱(re)(re)平衡。其工(gong)作原理是：當(dang)恒(heng)(heng)(heng)溫(wen)(wen)槽(cao)的熱(re)(re)量由(you)于對外散失(shi)而使(shi)其溫(wen)(wen)度降(jiang)低(di)時(shi)，恒(heng)(heng)(heng)溫(wen)(wen)控制(zhi)器就能驅使(shi)恒(heng)(heng)(heng)溫(wen)(wen)槽(cao)中(zhong)的電加(jia)熱(re)(re)器工(gong)作；待加(jia)熱(re)(re)到所(suo)需要的溫(wen)(wen)度時(shi)，它(ta)又會(hui)使(shi)其停止加(jia)熱(re)(re)，使(shi)恒(heng)(heng)(heng)溫(wen)(wen)槽(cao)溫(wen)(wen)度保(bao)持恒(heng)(heng)(heng)定。

  高低溫(wen)(wen)恒溫(wen)(wen)槽作(zuo)用是為(wei)(wei)用戶(hu)實驗(yan)(yan)和(he)生(sheng)產(chan)時提供(gong)一個熱冷受控，溫(wen)(wen)度均勻(yun)恒定(ding)的(de)場源(yuan)，對試(shi)驗(yan)(yan)樣品(pin)或(huo)(huo)(huo)生(sheng)產(chan)的(de)產(chan)品(pin)進行恒定(ding)溫(wen)(wen)度試(shi)驗(yan)(yan)或(huo)(huo)(huo)測試(shi)，也可作(zuo)為(wei)(wei)直接(jie)加熱或(huo)(huo)(huo)制冷和(he)輔助(zhu)加熱或(huo)(huo)(huo)制冷的(de)熱源(yuan)或(huo)(huo)(huo)冷源(yuan)。
