潮濕冷凝環(huán)境
在很多戶外環(huán)境中，材料每天的潮濕時間可長達(dá)12小時。研究表明造成這種戶外潮濕的主要因素是露水，而不是雨水。Q8/UV通過*的冷凝功能來模擬戶外的潮濕侵蝕。在試驗(yàn)過程中的冷凝循環(huán)中，測試室底部蓄水池中的水被加熱以產(chǎn)生熱蒸氣，并充滿整個測試室，熱蒸汽使測試室內(nèi)的相對濕度維持在100％，并保持一個相對高溫。試樣被固定在測試室的側(cè)壁，從而試樣的測試面曝露在測試室內(nèi)的環(huán)境空氣中。試樣向外的一面暴露在自然環(huán)境中具有冷卻效果，導(dǎo)致試樣內(nèi)外表面具備溫差，這一溫差的出現(xiàn)導(dǎo)致試樣在整個冷凝循環(huán)過程中，其測試面始終有冷凝生成的液態(tài)水。
由于戶外曝曬接觸潮濕的時間每天可以長達(dá)十幾小時，因此典型的冷凝循環(huán)一般持續(xù)幾個小時。Q8/UV提供兩種潮濕模擬方法。應(yīng)用zui多的是冷凝方法，它是模擬戶外潮濕侵蝕的方法。所有的Q8/UV型號都可運(yùn)行冷凝循環(huán)。因?yàn)橛行?yīng)用條件也要求使用水噴淋以達(dá)到實(shí)際的效果，所以有些Q8/UV型號既可運(yùn)行冷凝循環(huán)又可運(yùn)行水噴淋循環(huán)。

溫度控制
在每個循環(huán)中，溫度都可控制在一個設(shè)定值。同時黑板溫度計可以監(jiān)控溫度。溫度的提高可以加速老化的進(jìn)程，同時，溫度的控制對于測試的可再現(xiàn)性也是很重要的。

水噴淋系統(tǒng)
對于某些應(yīng)用而言，水噴淋能更好地模擬zui終使用的環(huán)境條件。水噴淋在模擬由于溫度劇變和由于雨水沖刷所造成的熱沖擊或機(jī)械侵蝕是非常有效的。在某些實(shí)際應(yīng)用條件下，例如陽光下，聚集的熱量由于突降的陣雨而迅速消散時，材料的溫度就會發(fā)生急劇變化，產(chǎn)生熱沖擊，這種熱沖擊對于許多材料而言是一種考驗(yàn)。Q8/UV的水噴淋可以模擬熱沖擊和/或應(yīng)力腐蝕。
噴淋系統(tǒng)有12個噴嘴，在測試室的每一邊各有6個；噴淋系統(tǒng)可運(yùn)行幾分鐘然后關(guān)閉。這短時間的噴水可快速冷卻樣品，營造熱沖擊的條件。

照射強(qiáng)度控制：可選
選配照射強(qiáng)度控制選件可得到精確型和重復(fù)性好的測試結(jié)果；光強(qiáng)控制系統(tǒng)允許用戶根據(jù)不同的測試要求設(shè)置不同的光照強(qiáng)度。通過其反饋回路裝置精確控制照射強(qiáng)度；同時也可以延長熒光燈的使用壽命
