The LF-200 zirconia oxygen analyzer was developed for automatic gas filling packaging equipment based on Toray Engineering's long track record with oxygen analyzers for the food packaging industry.
This analyzer is equipped with our unique, compact zirconia sensor to enable stable and highly accurate measurement over the long term, and an oxygen sensor protection mechanism for unprecedented durability. This is an easy to operate, compact oxygen analyzer which is ideal for integration into automatic packaging equipment for foods, pharmaceuticals and other products.

Features

• Protection against oils

The system is equipped with a new type of filter to improve measurement of gases with dispersed oils. The filter can be replaced without removing the analyzer from the panel.

• Suction pump protection function

Enables pump protection while avoiding problems due to on-site cleaning caused by blowing air.

• High-speed response

Internal pipe flow which minimizes gas stagnation at points of measurement.

• Power supply

AC200V is provided standard, for ease of integration into packaging equipment (AC100V is optional).
