選擇購買負(fù)離子檢測儀的時(shí)候，應(yīng)著重考慮的幾個(gè)問題！-深圳市鴻泰環(huán)?？萍加邢薰?/title> <META NAME="Keywords" CONTENT="負(fù)離子檢測儀"> <META NAME="Description" CONTENT=" 　　空氣離子濃度儀是吸引空氣(或者帶有離子存在的氣體)通過帶電的平行極化電極板進(jìn)行計(jì)數(shù)空氣中的離子(氣體)濃度的。外側(cè)二板保持極化(正、負(fù))電勢。中間是線性檢測器板。通過空氣的孔隙是4MM，極化區(qū)的電勢是1000V/M。既可測定正離子，又可測定負(fù)離子。"> <link href="/skins/418775/css/css.css"

　　空氣離子濃度儀是吸引空氣(或者帶有離子存在的氣體)通過帶電的平行極化電極板進(jìn)行計(jì)數(shù)空氣中的離子(氣體)濃度的。外側(cè)二板保持極化(正、負(fù))電勢。中間是線性檢測器板。通過空氣的孔隙是4MM，極化區(qū)的電勢是1000V/M。既可測定正離子，又可測定負(fù)離子。<div>　　現(xiàn)如今社會(huì)上充斥著大量的各種型號(hào)的空氣負(fù)離子檢測儀，其基本的工作原理都是一樣的，在選擇購買負(fù)離子檢測儀的時(shí)候，應(yīng)該著重考慮以下幾個(gè)問題。</div><div>　　1.測量范圍</div><div>　　根據(jù)項(xiàng)目的實(shí)際需要，選擇空氣負(fù)離子檢測儀檢測離子濃度上限，即大檢測量程。針對(duì)目前各種項(xiàng)目的需求，空氣負(fù)離子檢測儀檢測上限只要達(dá)到109個(gè)/cm3就足夠了。</div><div>　　2.靈敏度</div><div>　　所需要的離子濃度小分辨率，即檢測儀的靈敏度。如果在實(shí)際實(shí)驗(yàn)過程中，要求進(jìn)行空氣離子濃度檢測，則要求選用20個(gè)/cm3儀器，否則就會(huì)出現(xiàn)由于靈敏度不夠而影響測量結(jié)果的情況。</div><div>　　3.響應(yīng)時(shí)間</div><div>　　是指被測量的其他從開始被抽入收集器到儀器顯示數(shù)據(jù)指示穩(wěn)定所需的時(shí)間。在野外測試或被測試的離子源存在著較大的波動(dòng)時(shí)，選用相信時(shí)間長一些的儀器。但如果對(duì)于一些變化迅速的項(xiàng)目，就需要用到響應(yīng)時(shí)間較短的儀器。一般的情況下，響應(yīng)時(shí)間可在5-20S的范圍內(nèi)選擇。</div><div>　　4.測量誤差</div><div>　　主要是離子濃度測試誤差，離子濃度測試誤差主要是由微電流計(jì)的誤差和抽氣速率誤差組成。前者一般在5%左右，后者在10%左右，因此離子測量儀的誤差大致在15%-20%左右。</div><div>　　5.抽氣速率</div><div>　　是指儀器所用的抽氣機(jī)氣流速率，和儀器的取樣量直接相關(guān)。取樣量大的靈敏度一般較高，適宜于較大空間范圍的空氣進(jìn)行測試。取樣量曉得靈敏度較低，也較易受外界氣流干擾，但他同時(shí)對(duì)被測量對(duì)象影響也較小。</div><div>　　6.測量對(duì)象</div><div>　　空氣負(fù)離子檢測儀的測量對(duì)象，大體上可分為人造離子源和自然離子源。人造離子源主要有各種電暈式離子發(fā)生器、水激式負(fù)離子發(fā)生器及放射源離子發(fā)生器等。自然離子源，主要有地表放射性物質(zhì)、放射性氣體、宇宙線、天然瀑布及添加負(fù)離子的材料等。</div>
