Three Gas Analyzer

The F-950 Three Gas Analyzer measures levels of Ethylene, CO2 and O2 to maintain optimal produce quality at every phase of the supply chain.
The F-950’s versatile design allows it
to be be scaled to many environments, from cold storage to transportation container. 

Simple to operate and weighing less than a kilogram, the F-950 uses an electrochemical cell to measure ethylene between 0-200 ppm.
The F-950 is ideal for measuring ethylene production across a wide range of fruit types.


  • Measures C2H4, CO2 and O2
  • Displays results in under 30 seconds
  • Past records stored on the device
  • Handheld and lightweight
  • Internal data logging and storage (4GB SD card)
  • Battery lasts for 8+ hours
  • Display easily viewed in dimly lit environments
  • PolarCept!TM water filter for removing non-ethylene hydrocarbons
