经典款华瑞四合一气体检测仪PGM-2400以超高的性价比，简单实用，以及设置简便等优点，公司具有良好的市场信誉,专业的销售和技术服务团队,凭着经营华瑞气体检测仪QRAEII多年经验，安全使用，无后顾之忧。
华瑞四合一气体检测仪可同时显示4种气体或1种气体的数值指标量，当现场某种待检气体的指标处于报警范围时，PGM-2400会自动进行一系列报警动作，闪灯、振动、发声。QRAEII具备1个LEL传感器检测可燃气、2个EC传感器检测有毒气体、1个SPE传感器检测氧气。QRAEII传感器名称（多四个）、实时检测值，所有检测的高和低值、TWA/STEL值（氧气和可燃气除外）、电池电压、仪器运行时间，数据采集开/关状态。
华瑞四合一气体检测仪QRAEII是一个可检测多种有毒有害气体的便携式四合一检测仪，可同时对可燃气、氧气和有毒气体进行检测。
QRAEII兼容扩散和泵吸两种工作方式，适合不同应用场所。
华瑞四合一气体检测仪体积小巧，操作方便，内置中文菜单，更适合中国用户使用。
PGM-2400屏幕人性化翻转显示设计，方便观察。
华瑞气体检测仪QRAEII可同时安装几种传感器进行检测：
1）华瑞四合一气体检测仪QRAEII催化燃烧传感器检测可燃性气体
2）PGM-2400电化学传感器检测硫化氢、一氧化碳等有毒气体
3）QRAEII固体电解质（SPE）传感器检测氧气，比传统的电化学传感器寿命更长、性能更稳定。
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.
