GX-2012 5-in-1 Gas Monitor
五合一气体监测仪
GX-2012 围绕高质量的微传感器技术构建，是 RKI 最小的带有内置采样泵的个人 5 传感器气体监测仪。仅重 350 克，两种操作模式：普通（用于密闭空间）和酒吧孔。GX-2012 可以监测标准密闭空间气体（LEL 可燃物、氧气含量、一氧化碳和硫化氢），它还可以测量 100% 体积的甲烷，并通过自动量程动态显示 % LEL 或 % 体积能力。GX-2012 可用于气体管线吹扫测试以及标准安全测试。
GX-2012 的大液晶显示屏显示所有气体读数、电池电量、当前时间，并在警报条件下自动背光。标准警报类型包括振动、视觉和声音警报，可以设置为锁定或非锁定。GX-2012 由微处理器控制，不断检查自身是否存在传感器连接、电池电量不足、电路故障、低流量和校准错误。GX-2012 可以在锂离子电池组或碱性电池组上互换运行。
电池更换简单，无需工具即可进入可拆卸电池盒或电池组。校准和通气测试间隔和提醒是用户可调节的，并且可以设置为在校准周期到期后进入警报或将用户锁定在正常测量模式之外。校准可以自动执行，也可以在单一校准模式下单独执行。GX-2012 还兼容经济型 DC2000_2012 单通道校准站。
