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.
