1、遗漏模式可全量程(ppm/LEL/%Volime)检测可燃性气体,并可自动调整,可视可听可感知的报警系统,操作简单,可一键式操作,并可对一氧化碳进行检测
2、密闭空间检测模式可检测氧气、一氧化碳、硫化氢、可燃性气体,并附高敏感的报警系统,数据下载、最大/最小检测值显示
3、Barhole 模式检测地下气体的泄露,再此模式下,检测到的可燃气体自动以%Volume显示检测结果
4、一氧化碳检测模式直接显示PPM,装入氧气传感器时即可对氧气进行检测
5、清除模式可以测量室内空气中的甲烷含量
6、嗅探器模式,通过半导体探针快速的检测甲烷遗漏量,可视指示器能够正确指出探针在管道的位置
7、压力密封模式 通过背面的传感器检测
