冷(leng)熱沖擊試驗箱(xiang)和高低溫試驗箱(xiang)的區別在哪里？

冷熱沖(chong)擊試(shi)驗(yan)箱主要是做高溫(wen)(wen)、低(di)(di)(di)溫(wen)(wen)的(de)試(shi)驗(yan)設備(bei)(bei)，其特殊(shu)性能表現在瞬間從高溫(wen)(wen)到低(di)(di)(di)溫(wen)(wen)、或低(di)(di)(di)溫(wen)(wen)到高溫(wen)(wen)的(de)轉換(huan)速(su)率(lv)(lv)，只需(xu)10秒內可從高溫(wen)(wen)150℃轉換(huan)至(zhi)低(di)(di)(di)溫(wen)(wen)-65℃，集成(cheng)電(dian)路三(san)溫(wen)(wen)測試(shi)設備(bei)(bei)廠家，恢復時間5分鐘以內完成(cheng)，這就(jiu)是冷熱沖(chong)擊試(shi)驗(yan)箱的(de)轉換(huan)速(su)率(lv)(lv)的(de)表現。
