Oxygen AnalyzersFor Food Packaging Products

LC-450F, LC-750F, LF-200

Model: LC-450F

  • Minute sample measurement: 3 ml sample volume - Uses compact sensor newly developed by Toray
  • Automatic sample suction - Easy to operate
  • Sampling methods are selectable for each sample.
  • Easy to determine when measurement has ended - A buzzer sounds to notify the operator that measurement has ended
  • Hygienic exterior - Hygienic design featuring a stainless steel cover and white panels + RoHS compliant, low power consumption - Environmentally conscious design

Model: LF-200

LF-200

  • Best for embedding in packaging systems
  • Can be switched between automatic continuous suction and syringe injection
  • Equipped with new filter to prevent from oil which makes performance greater when measuring gases containing dispersed oils.
    Filter can be replaced without removing the oxygen analyzer from the panel.
  • Equipped with a suction pump protecting function, it is possible to protect the pump by avoiding problems caused by on-site air blow cleaning.
  • Standard 200 V AC power for easy embedding in packaging systems (100 V AC is also available as an option).
