<div>　　<strong>激光粉塵檢測儀</strong>是一種高效、精確的粉塵濃度檢測儀器，它利用激光散射原理來測量空氣中的粉塵顆粒濃度。其工作原理是基于激光散射原理。當(dāng)激光器發(fā)出單色、平行、窄束的激光時，經(jīng)過透鏡后形成一定直徑的探測區(qū)域。當(dāng)空氣中的粉塵顆粒通過該探測區(qū)域時，會與激光發(fā)生散射，產(chǎn)生不同方向和強(qiáng)度的散射光。散射光探測器會安裝在探測區(qū)域周圍的特定角度，以收集這些散射光信號，并將其轉(zhuǎn)換為電信號。隨后，信號處理器會對這些電信號進(jìn)行放大、濾波、積分和分析，從而得出粉塵的濃度和粒徑分布數(shù)據(jù)，并通過顯示器顯示出來。</div><div>　<strong>　<a href="http://m.fshxyy.com/Products-38737269.html" target="_blank">激光粉塵檢測儀</a></strong>的日常保養(yǎng)主要包括以下幾個方面：</div><div>　　1、清潔工作</div><div>　　儀器外觀清潔：使用柔軟的布或棉球擦拭儀器表面，去除灰塵和污漬，避免在儀器上噴灑化學(xué)清潔劑。定期檢查儀器光學(xué)窗口是否被污染，一般建議在系統(tǒng)安裝后第3天s次檢查，30天后再次檢查，之后每三個月檢查一次。若發(fā)現(xiàn)儀器環(huán)境惡劣、光學(xué)窗口污染嚴(yán)重，需增加常規(guī)檢查頻次。</div><div>　　內(nèi)部清理：如果安裝在粉塵濃度較高的環(huán)境下，需要定期清理儀器內(nèi)部的粉塵，防止傳感器堵塞影響檢測?？墒褂梦鼔m器或畫筆等工具清除灰塵，再用濕布擦拭掉表面污漬。</div><div>　　2、校準(zhǔn)操作</div><div>　　靈敏度校準(zhǔn)：根據(jù)使用手冊的指導(dǎo)，定期使用校準(zhǔn)氣體進(jìn)行靈敏度校準(zhǔn)，保證儀器的準(zhǔn)確性。</div><div>　　讀數(shù)準(zhǔn)確度校準(zhǔn)：除了靈敏度校準(zhǔn)外，還需定期對儀器的讀數(shù)準(zhǔn)確度進(jìn)行校準(zhǔn)。使用標(biāo)準(zhǔn)氣體或?yàn)橐獪y試的環(huán)境設(shè)置適當(dāng)?shù)幕鶞?zhǔn)值，對儀器進(jìn)行零點(diǎn)和滿量程校準(zhǔn)，確保檢測的數(shù)字與實(shí)際情況相符。</div><div>　　3、零件檢查與更換</div><div>　　傳感器和過濾器：儀器的傳感器是精密元件，使用久了會出現(xiàn)損壞或性能下降的情況，應(yīng)定期檢查并及時更換損壞的部件。同時，對于有過濾器的儀器，也需定期檢查和更換過濾器，確保其過濾效果良好。</div><div>　　電池電量：如果粉塵檢測儀使用電池供電，要定期檢查電池電量。低電量會影響儀器的正常工作，應(yīng)及時更換電池以確保儀器的長期穩(wěn)定運(yùn)行。</div><div>　　4、環(huán)境防護(hù)</div><div>　　溫度控制：不要將儀器安裝在溫度超過60度以上的工作環(huán)境中，長期的高溫環(huán)境會對粉塵傳感器造成損壞，減短壽命。</div><div>　　防水防潮：在使用過程中注意不要讓儀器進(jìn)水，如果進(jìn)水會導(dǎo)致傳感器故障一直報(bào)警。</div><div>　　5、記錄與存儲</div><div>　　數(shù)據(jù)記錄：部分激光粉塵檢測儀具有數(shù)據(jù)存儲功能，應(yīng)定期查看和記錄檢測數(shù)據(jù)，以便后續(xù)分析和比較。</div><div>　　存儲條件：當(dāng)不使用儀器時，應(yīng)將其存放在干燥、通風(fēng)、溫度適宜的地方，避免陽光直射和高溫高濕環(huán)境。</div>
