style="text-indent:25px">高低溫測試對測試的具體溫度、高溫和低溫各自保持的時間、升溫和降溫的時間、測多少個周期等沒有固定的標準，委托方可以自己制定企業(yè)內(nèi)部標準，或按客戶要求制定測試條件。制定測試條件時可參考產(chǎn)品實際的存儲環(huán)境、運輸環(huán)境及使用環(huán)境等。常做的溫度是-30至70°C，溫度保持時間2小時至8小時不等，變溫時長一般半小時以內(nèi)，循環(huán)周期4至20個周期不等。高低溫測試的價格是按測試時長來報價，不同大小的產(chǎn)品對應(yīng)使用不同大小的溫度箱，不同大小的溫度箱有不同的測試單價，即每小時多少錢，然后乘以測試總時間。測試時間長則總價可以給予一定的折扣優(yōu)惠，測試時間短會有基本的開機費。合肥低溫試驗箱廠家高低溫試驗箱具有模擬大氣環(huán)境中溫度變化規(guī)律。</p><div

style="text-indent:25px">高低溫試驗箱的使用環(huán)境和操作原理與它使用的壽命長短有著直接的聯(lián)系，那我們在使用的時候應(yīng)該注意那些問題呢?為了保證我們使用過程中安全，下面我們大概講一下它的使用方法：1、在開箱的時候如果發(fā)現(xiàn)了機器損壞或變形，就不要使用了。2、在開機前一定要查看電源是否穩(wěn)定，為了防止觸電或者是產(chǎn)生誤動作和故障，我們在安裝和接線還沒結(jié)束前，千萬不要接通電源。3、禁止自己擅自拆卸、加工、改造或修理高低溫試驗箱，這會造成觸電或火災(zāi)的危險。4、儀表內(nèi)部零件都有它一定的壽命，為了讓我們更安全使用儀表，請定期做好保養(yǎng)及維護工作。5、要使用干布擦拭儀表，不要用任何液體(例：酒精、汽油)擦拭，更不能把水濺到儀表上，如不慎滲入水，請馬上停止使用，不然會有漏電及火災(zāi)的危險。</p><p style="text-indent:25px">高低溫測試是用帶加熱和制冷功能的可編程高低溫箱進行測試。測試前先檢查測試樣品的狀態(tài)，外觀、功能、性能等是否正常，并拍照；然后，將樣品放入高低溫箱中，設(shè)置溫度箱的高溫、低溫值及各自保持的時間、變溫的時間、周期數(shù)。比如高溫70°C下保持2小時，然后從70°C半小時內(nèi)降到低溫-20°C，保持2小時，再從-20°C半小時內(nèi)升溫到70°C。如此循環(huán)，測試20個循環(huán)。測完后，拿出樣品，檢查測試后樣品的外觀、功能、性能等。如發(fā)現(xiàn)樣品跟測試前相比無明顯變化，或者變化在所定的標準范圍之類，則表示測試樣品的抗高低溫循環(huán)性能符合要求，否則為不符合。低溫環(huán)境箱能對制冷系統(tǒng)的能耗及制冷量進行有效的調(diào)節(jié)。</p><div
