英GMI GT40可燃氣體檢測儀
1、遺漏模式可全量程（ppm/LEL/%Volime）檢測可燃性氣體,并可自動調整，可視可聽可感知的報警系統，操作簡單，可一鍵式a操作，并可對一氧化碳進行檢測
2、密閉空間檢測模式可檢測氧氣、一氧化碳、硫化氫、可燃性氣體，并附高敏感的報警系統，數據下載、zui大/zui小檢測值顯示
3、Barhole 模式檢測地下氣體的泄露，再此模式下，檢測到的可燃氣體自動以%Volume顯示檢測結果
4、一氧化碳檢測模式直接顯示PPM，裝入氧氣傳感器時即可對氧氣進行檢測
5、清除模式可以測量室內空氣中的甲烷含量
6、嗅探器模式，通過半導體探針快速的檢測甲烷遺漏量，可視指示器能夠正確指出探針在管道的位置
7、壓力密封模式 通過背面的傳感器檢測
