HORIBA MEXA-730λ：直插式空燃比計

?MEXA-730λ采用此性能，并增加了原始設(shè)計，以增強可見性和操作性。? ?新的傳感器系數(shù)數(shù)據(jù)存儲器功能使恢復(fù)備份數(shù)據(jù)成為可能，從而提供更快的啟動時間并節(jié)省寶貴的運行時間。

詳細介紹

概要

用來實現(xiàn)汽車發(fā)動機的理想燃燒狀態(tài)以及凈化汽車尾氣所必需的空燃比檢測設(shè)備。該設(shè)備凝聚了HORIBA最新的空燃比檢測技術(shù)。HORIBA　空燃比檢測技術(shù)在汽車排氣分析中具有世界領(lǐng)先地位，在全球擁有大量的用戶。大約80ms的高速響應(yīng)性，較寬的測量量程，小巧化的設(shè)計（容積和重量都只有原來的1／3），是汽車發(fā)動機研究、實時檢測等領(lǐng)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(fā)動機的空燃比、λ、氧氣濃度測量，一臺設(shè)備可以滿足多種用途。
