  • Easy to install and maintain
  • Suitable for wave and reflow systems

The Zr-OxEPC is a residual oxygen analyzer for use with soldering ovens and similar applications where a process needs to be carried out in an oxygen free environment. Typically the process chamber is purged with an inert gas such as Nitrogen or Argon in order to remove atmospheric oxygen from the process area.
The ZrOx use a sensitive zirconia sensor to detect residual oxygen down to the ppm levels. The sensor will not saturate which means it can be instantly responsive from high oxygen concentration such as atmospheric oxygen (20.9%) down to ppm levels in a matter of seconds. The instrument is self contained with a built in pump and sample lines ready to connect to the oven or glove box. Operation is achieved via a large touch screen user interface. The current oxygen concentration is displayed in real time. Various digital and analog interface functions are possibly depending on the configuration of your system. There are built in alarms and relays that can be interfaced with your machine. There is an optional USB interface for data logging to a PC or PLC.
