Oxygen Analyzer Rapidox 1100Z

Oxygen Analyzer Rapidox 1100Z

Zirconia oxygen sensors are common solutions for providing fast and accurate gas analysis over the low ppm oxygen range. They are particularly suitable for monitoring inert atmospheres and aggressive industrial applications within manufacturing processes.

Configuration of the analyser allows for the instrument to be panel mounted with the gas fittings at either the front or rear. Other variations of the analyser include a three-channel multiplex version, which allows for three gas streams to be sampled from separate points. Gases can be analysed in sequence or at intervals set from the front keypad controls or software.

The Rapidox 1100 range can also be used to control an external proportional flow control valve (PFC) or a single solenoid relay using a remote signal output (RSO). These are exceptionally useful within inert gas blanketing applications, where the analyser can regulate the level of gas based on the measurement of oxygen via the PFC or RSO control function.

Though highly configurable to suit individual customer requirements, the Rapidox 1100 range possesses a number of standard features to enhance functionality

  • Low maintenance zirconia sensor
  • Fully configurable software
  • Fast and accurate response
  • Simple calibration procedure
  • Fully programmable outputs
  • Data logging
  • Pump or ejector option
  • Two programmable alarms
  • Operates on worldwide mains voltage
  • Password protection
