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.
LC-750L/PC-120
Built-in type Oxygen Analyzer for low concentration clean gas
LC-300
High-functionality Oxygen Analyzer
Ideal for control/monitoring in semiconductor applications, all types of experiments and research, and process control for atmosphere treatment and baking.
RF-30
Oxygen analyzer for baking furnaces and N2 reflow ovens. Easy to operate, compact and ideal for integrated installation. Equipped with a zirconia sensor.
