便攜式無線可視粉塵檢測儀（單監(jiān)測器，0.01 - 200 mg/m3，美國） 型號:T9M74611-A（H1直購）庫號：M74611 標準配置：
注意：該儀器可以zui多配4個監(jiān)測器。（根據客戶要求定制，標配中含一個監(jiān)測器）
測量有害粉塵危害程度等級，同時錄像工人工作情況，
友好人機窗口界面，操作簡單。
該儀器可以監(jiān)測工人的肺部損害程度，并且可以視頻，錄音，存儲錄像和檢測粉塵數據，這對工人健康狀況非常關鍵。
核生化事故影響了重工業(yè)污染空氣監(jiān)測計劃。一體化的視頻系統(tǒng)測量污染微粒可以更有效地進行確認和分析暴露的空氣污染物。這可以更好地控制和改進方案。
應用
*確定各級的工人呼吸保護，符合OSHA規(guī)定
*遵守程序審查
*評價工作的做法和控制的灰塵產生的方案
*安全審計
* NIOSH視頻曝光監(jiān)測實時圖形疊加
*接觸焊接煙塵
*空氣質量研究的職業(yè)衛(wèi)生和工業(yè)衛(wèi)生
