經(jīng)典款華瑞四合一氣體檢測儀PGM-2400以超高的性價比,簡單實用,以及設置簡便等優(yōu)點,公司具有良好的市場信譽,專業(yè)的銷售和技術(shù)服務團隊,憑著經(jīng)營華瑞氣體檢測儀QRAEII多年經(jīng)驗,安全使用,無后顧之憂。
華瑞四合一氣體檢測儀可同時顯示4種氣體或1種氣體的數(shù)值指標量,當現(xiàn)場某種待檢氣體的指標處于報警范圍時,PGM-2400會自動進行一系列報警動作,閃燈、振動、發(fā)聲。QRAEII具備1個LEL傳感器檢測可燃氣、2個EC傳感器檢測有毒氣體、1個SPE傳感器檢測氧氣。QRAEII傳感器名稱(多四個)、實時檢測值,所有檢測的高和低值、TWA/STEL值(氧氣和可燃氣除外)、電池電壓、儀器運行時間,數(shù)據(jù)采集開/關(guān)狀態(tài)。
華瑞四合一氣體檢測儀QRAEII是一個可檢測多種有毒有害氣體的便攜式四合一檢測儀,可同時對可燃氣、氧氣和有毒氣體進行檢測。
QRAEII兼容擴散和泵吸兩種工作方式,適合不同應用場所。
華瑞四合一氣體檢測儀體積小巧,操作方便,內(nèi)置中文菜單,更適合中國用戶使用。
PGM-2400屏幕人性化翻轉(zhuǎn)顯示設計,方便觀察。
華瑞氣體檢測儀QRAEII可同時安裝幾種傳感器進行檢測:
1)華瑞四合一氣體檢測儀QRAEII催化燃燒傳感器檢測可燃性氣體
2)PGM-2400電化學傳感器檢測硫化氫、一氧化碳等有毒氣體
3)QRAEII固體電解質(zhì)(SPE)傳感器檢測氧氣,比傳統(tǒng)的電化學傳感器壽命更長、性能更穩(wěn)定。
The QRAEII is a full-featured, compact, one- to four-sensor gas detector for oxygen, combustibles, hydrogen sulfide, or carbon monoxide. Key features include easy-to-change battery pack, a water-resistant case and a new state-of-the-art O2 sensor.
