Features 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. Main Specifications| Type |
