<strong>甲醛檢測儀</strong>的檢測原理為用采樣器采集一定體積的空氣，空氣中的甲醛與酚試劑反應，簡(jiǎn)稱(chēng)TH反應，生成嗪，在加入的顯色劑高鐵離子存在下，嗪與酚試劑的氧化產(chǎn)物反應生成藍綠色化合物，甲醛的含量與顯色深度成正比，可通過(guò)比色很好的識別。<div>產(chǎn)品特點(diǎn)：htV-m型甲醛檢測儀，采用*微電子及傳感器技術(shù)，具備濕度補償功能，即使在溫濕度較高的很端環(huán)境下htV-m型能夠準確地測量甲醛濃度。讀數以ppm或mg/m3單位顯示。也可以實(shí)時(shí)測量溫度及濕度。PPM公司隨機提供用于校準的甲醛校正源，用戶(hù)可以自行為檢測儀作現場(chǎng)校準及周期性校準，增加檢測儀的檢測精度。htV-m型是基本型(htV)上增加數據內存記憶及實(shí)時(shí)時(shí)鐘功能，配合AC適配器使用，可以在線(xiàn)連續地記錄7天的檢測數據，使htV-m型成為一臺可連續監測及具有數據記錄功能的甲醛檢測儀。</div><div>采樣方法：通過(guò)內置泵，采集10ml空氣樣品。</div><div>采樣頻率：1-3分鐘（取決于之前采集濃度）。</div><div>響應時(shí)間：低濃度大約8秒，高濃度大約60秒。</div><div>體積/重量：150x80x34mm/270g含電池。</div><div>注意事項：</div><div>1.每次檢測結束后應及時(shí)氣泡吸收瓶中有色溶液，再用酸洗液、自來(lái)水、蒸餾水清洗干凈。</div><div>2.氣泡吸收瓶且勿接入進(jìn)氣孔，否則會(huì )產(chǎn)生倒吸，損壞儀器，損失吸收液。</div><div>3.所有玻璃器具在第一次使用前，需用化學(xué)試驗室中的酸洗液、自來(lái)水、蒸餾水清洗干凈。</div> </div> </div> <div id="uockwsc" class="prev_next"> <ul> <li><p>上一篇：<a
