HORIBA MEXA-730λ：直插式空燃比計

?MEXA-730λ采用此性能，并增加了原始設計，以增強可見性和操作性。? ?新的傳感器系數數據存儲器功能使恢復備份數據成為可能，從而提供更快的啟動時間并節省寶貴的運行時間。

詳細介紹

概要

用來實現汽車發動機的理想燃燒狀態以及凈化汽車尾氣所必需的空燃比檢測設備。該設備凝聚了HORIBA最新的空燃比檢測技術。HORIBA　空燃比檢測技術在汽車排氣分析中具有世界領先地位，在全球擁有大量的用戶。大約80ms的高速響應性，較寬的測量量程，小巧化的設計（容積和重量都只有原來的1／3），是汽車發動機研究、實時檢測等領域的一種非常方便的便攜式空燃比分析儀，可以同時進行發動機的空燃比、λ、氧氣濃度測量，一臺設備可以滿足多種用途。
