Cost Reduction:

  • saves up to 30% of gas consumption by automatic controlling the required residual oxygen level to a pre-determined set point
  • the non-destructive gas analysis guarantees the quality of the packages and economy of the production

 Easy Operation:

  • simple calibration
  • low maintenance
  • easy to read display
  • integrated data logger
  • USB connection for file transfer
  • administration of product names
  • simple to operate via touchscreen
  • ethernet connection for network integration
  • measured data storage
  • user level with different access authorisation
  • user-definable settings for each different product i.e. setpoint, alarm limits etc.

 High Process Reliability:

  • data log
  • permanent control of the O2-concentration
  • electronic control of the sample gas to the sensor
  • lockable transparent door for protection of settings
  • alarm signals are given if the set limits are exceeded and a potential-free contact operates to e.g. auto-stop your machine to avoid quality problems
  • independent of pressure fluctuations in the gas supply
  • independent of packing speeds (MAP)
  • independent of package sizes (MAP)

Maximum Hygiene:

  • splash-proof, robust stainless steel housing
  • smooth and easy to clean surface


  • Interfaces for the documentation and remote transfer of the settings and measured values


  • software GAS CONTROL CENTER for a recording of results (see separate datasheet)
  • fully automatic calibration
  • bar code scanner for product names or user selection
  • additional memory
  • sample measurement via a needle – also with additional sensor
