GX-2012 5-in-1 Gas Monitor
五合一氣體監測儀
GX-2012 圍繞高質量的微傳感器技術構建，是 RKI 最小的帶有內置采樣泵的個人 5 傳感器氣體監測儀。僅重 350 克，兩種操作模式：普通（用于密閉空間）和酒吧孔。GX-2012 可以監測標準密閉空間氣體（LEL 可燃物、氧氣含量、一氧化碳和硫化氫），它還可以測量 100% 體積的甲烷，并通過自動量程動態顯示 % LEL 或 % 體積能力。GX-2012 可用于氣體管線吹掃測試以及標準安全測試。
GX-2012 的大液晶顯示屏顯示所有氣體讀數、電池電量、當前時間，并在警報條件下自動背光。標準警報類型包括振動、視覺和聲音警報，可以設置為鎖定或非鎖定。GX-2012 由微處理器控制，不斷檢查自身是否存在傳感器連接、電池電量不足、電路故障、低流量和校準錯誤。GX-2012 可以在鋰離子電池組或堿性電池組上互換運行。
電池更換簡單，無需工具即可進入可拆卸電池盒或電池組。校準和通氣測試間隔和提醒是用戶可調節的，并且可以設置為在校準周期到期后進入警報或將用戶鎖定在正常測量模式之外。校準可以自動執行，也可以在單一校準模式下單獨執行。GX-2012 還兼容經濟型 DC2000_2012 單通道校準站。
