Probe Electronics E713

General Information

The electronic unit E713 is the basic device for the use of ZIROX® oxygen probes.
The signals of ZIROX® probes are recorded with the E713, processed to the oxygen concentration according to the NERNST equation and provided by standard interface (4-20 mA). The E713 realizes the power supply and the heating control for heated ZIROX® probes.


  • Signal processing and measuring value display for ZIROX® probes
  • Measuring value output via standard interface
  • Power supply and heating control for heated ZIROX® probes
