步入(ru)式恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)房簡(jian)單點講就是(shi)大(da)型(xing)的恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)試驗箱，但其(qi)同恒(heng)(heng)(heng)(heng)溫(wen)(wen)(wen)(wen)(wen)恒(heng)(heng)(heng)(heng)濕(shi)試驗箱有很多區別。可(ke)(ke)以準確地模(mo)擬低溫(wen)(wen)(wen)(wen)(wen)、高溫(wen)(wen)(wen)(wen)(wen)、高溫(wen)(wen)(wen)(wen)(wen)高濕(shi)、低溫(wen)(wen)(wen)(wen)(wen)低濕(shi)復雜的自然狀環境，其(qi)主(zhu)要是(shi)用(yong)于(yu)檢(jian)測大(da)型(xing)的部件或元件，溫(wen)(wen)(wen)(wen)(wen)度(du)(du)范(fan)圍可(ke)(ke)做到-40℃～80℃（可(ke)(ke)交變溫(wen)(wen)(wen)(wen)(wen)度(du)(du)范(fan)圍：-40℃～60℃ ）；濕(shi)度(du)(du)范(fan)圍可(ke)(ke)做到30～98％R.H（可(ke)(ke)交變濕(shi)度(du)(du)范(fan)圍：45～98％R.H）。可(ke)(ke)定制

恒(heng)溫恒(heng)濕(shi)(shi)試(shi)驗箱又叫(jiao)高(gao)低溫交變濕(shi)(shi)熱試(shi)驗箱，區(qu)別在于名稱(cheng)不一(yi)樣，其功能，特性，原理，結(jie)構，用途，使(shi)用方法均一(yi)樣。可以準確地模擬低溫、高(gao)溫、高(gao)溫高(gao)濕(shi)(shi)、低溫低濕(shi)(shi)復雜(za)的自然狀(zhuang)環境，適用于塑膠、電子、食品、服裝、車輛、金屬、化學、建材，汽車零部(bu)件(jian)大(da)學科研單位等多種行業的產品可靠性檢(jian)測。
