><strong>激光粉塵儀</strong></a>該儀器適用于公共場(chǎng)所可吸入顆粒物（PM10）濃度的快速測定、工礦企業(yè)生產(chǎn)現場(chǎng)等勞動(dòng)衛生方面粉塵濃度的檢測，以及環(huán)境保護領(lǐng)域可吸入塵濃度的監測，還可用于空氣凈化器凈化效率的評價(jià)。近年來(lái)有千臺以上LD-3型儀器在全國各地使用，得到用戶(hù)好評。</p><p style="white-space: normal; text-indent: 2em; line-height: 1.75em;">儀器符合衛生部WS/T206-2001《公共場(chǎng)所空氣中可吸入顆粒物（PM10）測定法-光散射法》標準、勞動(dòng)部LD98-1996《空氣中粉塵濃度的光散射式測定法》標準以及鐵道部TB/T2323-92《鐵路作業(yè)場(chǎng)所空氣儀器中粉塵測定相對質(zhì)量濃度與質(zhì)量濃度的轉換方法》等行業(yè)標準以及衛生部衛監督發(fā)〔2006〕58號文件頒布實(shí)施的《公共場(chǎng)所集中空調通風(fēng)系統衛生規范》。LD-3H/L已獲得計量器具型式批準證書(shū)。</p><h3 style="line-height: 1.75em;"><strong>激光光散射粉塵儀原理</strong><br/></h3><p style="line-height: 1.75em;">利用激光光束照射到含塵氣流上，使光束產(chǎn)生散射光，粉塵濃度越高，產(chǎn)生的散射光強度越大，由此測出粉塵濃度。光散射法測定公共場(chǎng)所空氣中可吸入顆粒物濃度，具有快速、靈敏、穩定性好、體積小、重量輕、無(wú)噪聲、操作簡(jiǎn)便、安全可靠等優(yōu)點(diǎn)。一方面該方法具有較高靈敏度而需要的樣品量少，并可省去或者簡(jiǎn)化樣品處理步驟，因此采樣時(shí)間和分析時(shí)間均可大大縮短；另一方面，該方法無(wú)需樣品儲存，從而避免或減少了分析方法中的各種可能的誤差因素。</p><h3 style="line-height: 1.75em;"><strong>主要技術(shù)特點(diǎn)</strong></h3><p style="line-height: 1.75em;">1、可直讀顆粒物質(zhì)量濃度（mg/m3），1分鐘出結果，或根據用戶(hù)需要任意設定采樣時(shí)間；</p><p style="line-height: 1.75em;">2、測量快速、準確、檢測靈敏度高；</p><p style="line-height: 1.75em;">3、設計了自校系統,儀器性能穩定可靠；</p><p style="line-height: 1.75em;">4、具有氣幕屏蔽及潔凈氣自清洗功能，確保光學(xué)系統不受污染；</p><p style="line-height:
