ZIROX Oxygen Measuring Module ZR5Properties For optimal quality and process control the avoidance of oxygen, even traces, is necessary in various technological applications. A constant monitoring and documentation of quality parameters becomes more important - not least because of the increasing introduction of quality assurance systems, e.g. ISO 9000. The oxygen measuring module ZR5 is based on the approved zirconia technology. It serves the continuous measurement of oxygen concentration in industry and laboratory gases and the monitoring of protective gases. Deviations of the oxygen concentration from setpoints can be signalized, the procedure of special production processes under inert gas can be monitored by the ZR5 module. Applications • Protective gas monitoring in food processing, e.g. in packaging • Protective gas monitoring in technological processes, e.g. soldering, welding • Monitoring tasks in microelectronics • Monitoring of protective and inert gases in surface treatment processes Sensoren und Elektronik GmbH^
