負離子測試儀選購的注意事項-深圳市鴻泰環(huán)?？萍加邢薰?/title> <META NAME="Keywords" CONTENT="負離子測試儀"> <META NAME="Description" CONTENT=" 　　負離子測試儀是一款快速測量空氣中負離子含量的檢測儀器?？諝庵械呢撾x子能還原大氣的污染物質、氮氧化物等產生的活性氧、減少過多活性氧對人體的危害。負離子不僅能促成人體合成和儲存維生素，強化和激活人體的生理活動，因此又被稱為“空氣維生素”。負離子測試儀可快速測量出空氣中的負離子含量，為判斷空氣質量情況提供參考依據。"> <link href="/skins/418775/css/css.css"

　　負離子測試儀是一款快速測量空氣中負離子含量的檢測儀器?？諝庵械呢撾x子能還原大氣的污染物質、氮氧化物等產生的活性氧、減少過多活性氧對人體的危害。負離子不僅能促成人體合成和儲存維生素，強化和激活人體的生理活動，因此又被稱為“空氣維生素”。負離子測試儀可快速測量出空氣中的負離子含量，為判斷空氣質量情況提供參考依據。<div>　　負離子測試儀操作簡單，移動測量、即開即測，使用十分方便。按下“開關按鍵”聽到“滴”聲（一聲）開機，等待30秒自檢完成進入主界面，選擇檢測模式，儀器即可測量空氣中負離子個數，測量數值直接顯示在液晶屏中心，并以1秒為周期連續(xù)刷新。</div><div>　　負離子檢測儀是檢測空氣環(huán)境中負氧離子、溫度、濕度實時濃度及變動的系統(tǒng)設備，具有可靠性高、高準確度、易維護保養(yǎng)、易備份等特征。因而該設備能滿足環(huán)境氣象監(jiān)測的業(yè)務要求，滿足檢測數據的高精度和高穩(wěn)定度要求。今日小編主要來介紹一下該產品選購的注意事項。</div><div>　　1、用途</div><div>　　現如今負離子檢測儀的種類多樣，應用的地方也是許多不一樣，進而需要在選購以前確定自己運用該設備是將會用在什么地方且周圍環(huán)境怎么樣，在此前提之下再進行其他方面的考慮才能夠選擇到適合的設備。</div><div>　　2、服務品質</div><div>　　選購的人不一定會對負離子檢測儀有足夠的了解，當出現故障時也不一定會維修，因而選購時還需選擇服務品質好的產品，如此一來檢查儀得到賣家售后的品質保障，及其當出現問題的時候還能夠利用專業(yè)的人員進行及時的維修，以便于更快的再次投入應用當中。</div><div>　　3、商家是否正規(guī)</div><div>　　選購時所選擇的商家是不是經過正規(guī)的認證進而合法的經營銷售該產品也是需要注意的，進而需要事先調查了解將要選購的這個廠家是不是通過正規(guī)的部門認證才從業(yè)該項經營活動的，隨后在決定是不是要選購，防止購買到品質一般的產品。</div><div>　　選擇正規(guī)適合自己的負離子檢測儀能夠確保數據的準確度，上述對于選擇的幾項能夠作為參考。</div><div>
