Zirconia Sensors

Toray’s zirconia oxygen analyzers achieve quick response and theoretical output, which is valued highly in many applications such as the check of residual oxygen by trace gas in food packages, the control and monitoring of processing atmosphere in metal or semiconductor production, combustion control, cultivation and fermentation.

Toray zirconia oxygen analyzers determine oxygen concentration using the conductifity of a zirconia ceramic cell.
