選購恒溫恒濕試驗箱如何避免踩雷？

      恒(heng)溫恒(heng)濕試驗箱電(dian)(dian)源(yuan)選擇(ze)不(bu)管是(shi)220V還是(shi)380V都是(shi)三相以上電(dian)(dian)源(yuan)接口的，如果(guo)溫度在-40度以下，而且箱體(ti)在225L以上的，建議選擇(ze)380V四(si)相電(dian)(dian)源(yuan)接口，因這樣對整個實驗室的用(yong)電(dian)(dian)比較穩定，對設備(bei)本身(shen)的壽命也有好處。

　    尺寸選擇(ze)一(yi)般(ban)恒溫(wen)恒濕(shi)尺寸根據試驗產(chan)品的尺寸來決定 。

　　風冷(leng)與水冷(leng)選擇：恒溫(wen)恒濕試驗(yan)箱一般(ban)采(cai)用(yong)風冷(leng)就足夠了，采(cai)用(yong)水冷(leng)的(de)(de)一般(ban)是大型的(de)(de)恒溫(wen)恒濕室或大箱體的(de)(de)快速升降(jiang)溫(wen)試驗(yan)機(ji)，一般(ban)冷(leng)熱沖擊(ji)試驗(yan)箱采(cai)用(yong)水冷(leng)的(de)(de)比較多(duo)。

　　恒(heng)溫恒(heng)濕試(shi)(shi)驗(yan)(yan)(yan)(yan)箱使(shi)用環(huan)境(jing)環(huan)境(jing)試(shi)(shi)驗(yan)(yan)(yan)(yan)，特(te)別是可(ke)靠性試(shi)(shi)驗(yan)(yan)(yan)(yan)，試(shi)(shi)驗(yan)(yan)(yan)(yan)周期長，試(shi)(shi)驗(yan)(yan)(yan)(yan)的對(dui)象(xiang)有(you)(you)時是價值很(hen)高的產品，試(shi)(shi)驗(yan)(yan)(yan)(yan)過程(cheng)中，試(shi)(shi)驗(yan)(yan)(yan)(yan)人(ren)員經常(chang)要在現場周圍(wei)進行操作或(huo)測試(shi)(shi)工作，因此要求(qiu)環(huan)境(jing)試(shi)(shi)驗(yan)(yan)(yan)(yan)設備必須具有(you)(you)運行安全(quan)、操作方便、使(shi)用可(ke)靠、工作壽(shou)命(ming)長等特(te)點，以確保試(shi)(shi)驗(yan)(yan)(yan)(yan)本身(shen)的正常(chang)進行。試(shi)(shi)驗(yan)(yan)(yan)(yan)設備的各種保護、告警措施及安全(quan)聯鎖裝置應(ying)該完善(shan)可(ke)靠，以保證試(shi)(shi)驗(yan)(yan)(yan)(yan)人(ren)員、被試(shi)(shi)產品和試(shi)(shi)驗(yan)(yan)(yan)(yan)設備本身(shen)的安全(quan)可(ke)靠性。
