華瑞氣體檢測(cè)儀QRAEII可同時(shí)安裝幾種傳感器進(jìn)行檢測(cè)：
1）華瑞四合一氣體檢測(cè)儀QRAEII催化燃燒傳感器檢測(cè)可燃性氣體
2）PGM-2400電化學(xué)傳感器檢測(cè)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(cè)氧氣，比傳統(tǒng)的電化學(xué)傳感器壽命更長(zhǎng)、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.
