步入式濕熱環境試驗室性能參數(shu):
1.溫度控制范圍:A： 0～80℃（100℃）；B：-20～+80℃（100℃）；C：-40～+80℃（100℃）；D：-70～+80℃（100℃）
2.升溫速率: RT+10℃→+80℃ ≤30 min（非線性空載）
3.降溫速(su)率(lv): +20℃→-70℃ ≤100 min（非線性空載(zai)）

※ 溫(wen)(wen)度變化速率為空氣(qi)溫(wen)(wen)度變化速率,而非產品溫(wen)(wen)度變化速率

4.溫控波動(dong)度:±0.5℃.
5.溫控均勻度:±2.0℃.

步入式溫(wen)控箱|步入式(shi)溫控試驗室(shi)常(chang)見故障(zhang)排除
1.在高溫控(kong)(kong)制(zhi)試(shi)驗(yan)中(zhong)，如(ru)溫度(du)(du)(du)變化(hua)達不到(dao)試(shi)驗(yan)溫度(du)(du)(du)值(zhi)時，可以檢查電(dian)器系(xi)統，逐(zhu)一(yi)(yi)排除故障(zhang)(zhang)。如(ru)溫度(du)(du)(du)升(sheng)得很慢，就要(yao)查看風循(xun)環(huan)(huan)系(xi)統，看一(yi)(yi)下風循(xun)環(huan)(huan)的(de)調節擋板是否開啟正(zheng)(zheng)常，反之，就檢查風循(xun)環(huan)(huan)的(de)電(dian)機運轉是否正(zheng)(zheng)常。如(ru)溫度(du)(du)(du)過沖厲(li)害那么(me)就需要(yao)整(zheng)定PID 的(de)設置參數。如(ru)果(guo)溫度(du)(du)(du)直接(jie)上(shang)升(sheng)，過溫保護，那么(me)，控(kong)(kong)制(zhi)器出(chu)故障(zhang)(zhang)，須更換控(kong)(kong)制(zhi)儀表。
2.低溫(wen)控制達不(bu)到(dao)試(shi)(shi)驗(yan)(yan)的(de)(de)(de)指標，那(nei)你就(jiu)要(yao)(yao)(yao)觀察溫(wen)度(du)的(de)(de)(de)變化，是(shi)(shi)溫(wen)度(du)降的(de)(de)(de)很慢，還(huan)是(shi)(shi)溫(wen)度(du)到(dao)一(yi)定(ding)值后(hou)溫(wen)度(du)有回升的(de)(de)(de)趨勢，前(qian)者就(jiu)要(yao)(yao)(yao)檢(jian)查一(yi)下，做低溫(wen)試(shi)(shi)驗(yan)(yan)前(qian)是(shi)(shi)否將(jiang)工(gong)(gong)作(zuo)室烘干，使工(gong)(gong)作(zuo)室保(bao)持干燥后(hou)再將(jiang)試(shi)(shi)驗(yan)(yan)樣品放(fang)入工(gong)(gong)作(zuo)室內(nei)再做試(shi)(shi)驗(yan)(yan)，工(gong)(gong)作(zuo)室內(nei)的(de)(de)(de)試(shi)(shi)驗(yan)(yan)樣品是(shi)(shi)否放(fang)置的(de)(de)(de)過多，使工(gong)(gong)作(zuo)室內(nei)的(de)(de)(de)風(feng)不(bu)能充分循(xun)環，在(zai)排(pai)除上述原(yuan)因后(hou)，就(jiu)要(yao)(yao)(yao)考慮是(shi)(shi)否是(shi)(shi)制冷系統中的(de)(de)(de)故(gu)障了，這樣就(jiu)要(yao)(yao)(yao)請廠家的(de)(de)(de)專(zhuan)業人(ren)員(yuan)進行(xing)檢(jian)修(xiu)。后(hou)者的(de)(de)(de)現象是(shi)(shi)設備的(de)(de)(de)使用(yong)環境(jing)不(bu)好所致，設備放(fang)置的(de)(de)(de)環境(jing)溫(wen)度(du)，放(fang)置的(de)(de)(de)位置（箱體后(hou)與墻的(de)(de)(de)距離(li)）要(yao)(yao)(yao)滿足要(yao)(yao)(yao)求（在(zai)設備操(cao)作(zuo)使用(yong)說明中都有規(gui)定(ding)）。
