style="text-indent:25px">高低溫試驗(yàn)箱與液氮深冷低溫箱的區(qū)別：環(huán)境試驗(yàn)設(shè)備高低溫系列試驗(yàn)箱種類繁多，*從外觀來看，可能沒有太大的區(qū)別，然而，它們所做的試驗(yàn)卻相差很大。我們就以高低溫試驗(yàn)箱和液氮深冷低溫箱來做比較，了解一下兩者之間的異同點(diǎn)。（1）溫度范圍：高低溫試驗(yàn)箱與液氮深冷低溫箱的比較大區(qū)別就是它們的溫度范圍不一樣，高低溫試驗(yàn)箱的溫度范圍可做到-80℃~150℃；而液氮深冷低溫箱的溫度范圍可做到-196℃~150℃。（2）制冷方式的不同：液氮深冷低溫箱是將液氮直接噴在試驗(yàn)箱箱體內(nèi)部，液氮在試驗(yàn)箱內(nèi)部吸熱蒸汽化，帶走熱量，使試驗(yàn)箱降溫；而高低溫試驗(yàn)箱則是將制冷系統(tǒng)的蒸發(fā)器設(shè)計(jì)在試驗(yàn)箱內(nèi)，經(jīng)過節(jié)流裝置的制冷劑在蒸發(fā)器內(nèi)部（不是直接進(jìn)入試驗(yàn)箱）蒸發(fā)汽化，吸收蒸發(fā)器**的熱量，使試驗(yàn)箱降溫；（3）溫變速率的不同：液氮深冷低溫箱的降溫速率非常快，可達(dá)到10℃/min；而高低溫試驗(yàn)箱的降溫速率為0，江蘇高低溫實(shí)驗(yàn)箱品牌.7~1℃/min。（4）高低溫試驗(yàn)箱的應(yīng)用范圍很廣，江蘇高低溫實(shí)驗(yàn)箱品牌，幾乎各行各業(yè)都會用到，江蘇高低溫實(shí)驗(yàn)箱品牌，而液氮深冷低溫箱只適用于特種行業(yè)。低溫環(huán)境箱的每一個(gè)系統(tǒng)與零配件都需要進(jìn)行查漏與維修。江蘇高低溫實(shí)驗(yàn)箱品牌</p><div
