    摘要:前不久,有媒體公布了上海市場監管部門對便攜式檢測儀的風險監測情況,41批次檢測儀都不靠譜的結果讓人意外。**檢測儀市場良莠不齊,該怎么選擇呢?

    甲醛、PM顆粒,看不見、摸不著,危害卻甚大。隨著消費者對居家、工作、生產環境的要求日益提高,各種空氣質量檢測儀成為“網紅”商品。便攜式甲醛檢測儀、輻射檢測儀、PM檢測儀……登錄淘寶網,輸入“檢測儀”,顯示出數百個頁面。以甲醛檢測儀為例,手持便攜式、臺式,款式多樣,價格低的幾十元,高的兩萬余元。不少甲醛檢測儀的商品頁面顯示,其檢測精度達到0.01PPM,即能檢測到微克每立方米甲醛。


    但上海市場監管部門曾對41批次網上購買的便攜式檢測儀的計量準確程度進行檢驗,結果顯示,這些檢測儀在同樣的環境中顯示的結果并不一樣。市面上的檢測儀產品良莠不齊、種類繁多,用戶應該怎么挑選呢?


    一、了解自己的需求
    選擇氣體檢測儀首先要明確檢測什么氣體?在什么環境中使用?便攜式的還是固定式?以及其他附帶的功能。這些原因通常是必須要考慮的。否則會出現本來打算買氧氣檢測儀結果買到了臭氧檢測儀,這就鬧了個大烏龍,不經耽誤事,還會造成不必要的經濟損失。


    二、了解使用環境的工況
    各類氣體檢測儀都有對現場環境的嚴格要求,一般來講溫度-20~60℃,濕度0-95%RH,壓力80-120Kpa等等,包括粉塵、流量等都有嚴格要求。因為環境中的其他雜質會對檢測結果產生巨大影響,導致不可預見到損失。同時了解現場的工況及時向廠家提供該信息,廠家都會有相應的方案來解決。


    三、了解現場安全情況
    多少情況下,氣體檢測儀安裝使用的現場都有防爆等強制要求。煤炭、石油和化工行業對防爆要求非常嚴格,需要儀器本身防爆同時帶有防爆認證。其他的環境可能要求氣體檢測儀有環保認證或者計量器具許可證等證件。


    四、了解使用的功能性需求
    氣體檢測儀的一般功能就是檢測氣體濃度,超標報警等。但是很多客戶不僅需要這些功能。信號輸出是一方面,必要需要電流輸出,數字信號輸出,電壓輸出和開關量輸出等。可能還有一些其他特殊的要求如網絡接口和無線信號等。同時數據記錄和處理也是比較常見的需求。


    五、了解傳感器產地
    很多氣體檢測儀廠家的傳感器標稱是國外傳感器,其實不盡然。有一些用國產傳感器冒充進口傳感器來坑消費者。當遇到這類情況時,要仔細核對產品信息,必要時簽訂購銷合同來保障自己的權益。


    以上是為大家總結的選擇氣體檢測儀中應該注意到的問題。建議大家選擇正規品牌,直接從廠家購買。這樣售后等技術支持問題就會很好解決。深圳藍月 創立于2009年 是一家集生產、研發、銷售于一體的綜合性傳感器企業。通過多年努力和積累,我們擁有自主品牌BM(BLUEMOON)、MIC、LY等,產品品類超過30個,有適合空氣VOC/CO2/CO/PM2.5/溫濕度等參數檢測的BM3000、BM3030、BM3501、BM4021、BM5011、BMP、BM400-PM、BM-RHT等產品,也有適用于農業CO2和土壤環境檢測的BMG、BM-PH、BM-HT、BM-ST等產品,MIC和LY系列產品則主要針對水質和空氣檢測分析市場,產品在大氣環境檢測、水質分析、工業氣體泄漏報警、危險應急檢測報警、消防預警等諸多領域都有大量穩定用戶。
