　　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(zhì)、氮氧化物等產(chǎn)生的活性氧、減少過(guò)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(dòng)，因此又被稱(chēng)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(zhì)量情況提供參考依據。"> <link

　　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(zhì)、氮氧化物等產(chǎn)生的活性氧、減少過(guò)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(dòng)，因此又被稱(chēng)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(zhì)量情況提供參考依據。<div>　　負離子測試儀操作簡(jiǎn)單，移動(dòng)測量、即開(kāi)即測，使用十分方便。按下“開(kāi)關(guān)按鍵”聽(tīng)到“滴”聲（一聲）開(kāi)機，等待30秒自檢完成進(jìn)入主界面，選擇檢測模式，儀器即可測量空氣中負離子個(gè)數，測量數值直接顯示在液晶屏中心，并以1秒為周期連續刷新。</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(shí)時(shí)濃度及變動(dòng)的系統設備，具有可靠性高、高準確度、易維護保養、易備份等特征。因而該設備能滿(mǎn)足環(huán)境氣象監測的業(yè)務(wù)要求，滿(mǎn)足檢測數據的高精度和高穩定度要求。今日小編主要來(lái)介紹一下該產(chǎn)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(lèi)多樣，應用的地方也是許多不一樣，進(jìn)而需要在選購以前確定自己運用該設備是將會(huì )用在什么地方且周?chē)h(huán)境怎么樣，在此前提之下再進(jìn)行其他方面的考慮才能夠選擇到適合的設備。</div><div>　　2、服務(wù)品質(zhì)</div><div>　　選購的人不一定會(huì )對負離子檢測儀有足夠的了解，當出現故障時(shí)也不一定會(huì )維修，因而選購時(shí)還需選擇服務(wù)品質(zhì)好的產(chǎn)品，如此一來(lái)檢查儀得到賣(mài)家售后的品質(zhì)保障，及其當出現問(wèn)題的時(shí)候還能夠利用專(zhuān)業(yè)的人員進(jìn)行及時(shí)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</div><div>　　選購時(shí)所選擇的商家是不是經(jīng)過(guò)正規的認證進(jìn)而合法的經(jīng)營(yíng)銷(xiāo)售該產(chǎn)品也是需要注意的，進(jìn)而需要事先調查了解將要選購的這個(gè)廠(chǎng)家是不是通過(guò)正規的部門(mén)認證才從業(yè)該項經(jīng)營(yíng)活動(dòng)的，隨后在決定是不是要選購，防止購買(mǎi)到品質(zhì)一般的產(chǎn)品。</div><div>　　選擇正規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>
