Type LC-850K, KS, KD


    The LC-850 series of high-functionality zirconia oxygen analyzers was designed based on Toray Engineering's long track record with oxygen analyzers, and enables measurement ranging from ultra-low concentrations to 100% oxygen concentration with a single device.
This series is equipped with our unique zirconia sensor to enable stable and highly accurate measurement over the long term. It can be used in virtually any application, from research to built-in operation in online equipment.
