負離子測試儀是用于測量空氣中負氧離子含量的裝置，它在多個領域都具有重要的應用價值。負氧離子分析儀采用電容式吸入法原理來測量空氣中的負離子濃度值。能夠實時、準確地提供負氧離子濃度的數據，對于評估和改善空氣質量、研究環境生態等方面具有重要意義。
一、產品簡介
FT-FY1型便攜式負（氧）離子檢測儀是一款高精度、專業型空氣負離子檢測、分析儀器。采用先進的圓筒電容結構負（氧）離子捕獲機制，將大氣中所含有負（氧）離子捕獲，然后通過算法，進行精確統計計算。具備測量過程穩定，反應迅速，測量結果準確等優點。同時具備很強的抗電磁、靜電、電磁波干擾能力，對小粒徑負離子有敏感性和捕捉能力，整體性能優。
FT-FY1型便攜式負（氧）離子檢測儀操作簡單，5.0英寸全彩大屏顯示實時測量數據、儀器工作狀態、自動計算平均值。操作人員無需專業培訓也可快速測量。
二、產品應用
實時測量空氣中的大氣負氧離子濃度是環境監測、納米涂料、負離子保健產品、負離子家裝建材、室內檢測、空氣治理、空氣凈化器及其制品負離子濃度的測量與演示的優選工具。
三、工作原理
采用“電容式吸入法”原理進行負離子檢測，測量空氣中的負離子濃度值。在離子傳感器（或稱采集桶、采集筒）的極化板（或稱偏壓板）上加載定量的極化電壓，再讓被測空氣按設定速度勻速通過傳感器。空氣中特定的小粒徑負離子在電場的作用下發生偏轉，被采集板所捕獲。采集到的負離子負電荷量經過采集器的處理，即可計算出負離子的電荷濃度值。
