Baking and N2 Reflow Use RF-400


The RF-400 zirconia oxygen analyzer was developed for use with N2 reflow equipment based on Toray Engineering's long track record with oxygen analyzers for the electronics 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 N2 reflow equipment and other types of equipment.
