O2/CO2/C2H4 analysers

An essential tool for analysing and controlling gas levels in a Controlled-Atmosphere chamber

O2/CO2 analyser

Technology

The O2-CO2 analyser is entirely built by ABSOGER and consists of two sensors:

  • Oxygen: A zirconium monoxide cell with 0-5% resolution.
  • CO2: an infrared (NDIR) sensor with 0-5% resolution.

Applications

  • Monitoring and managing Controlled Atmosphere chambers
  • Monitoring refrigerated containers
  • Gas detection
  • Analysing fruit respiration

Technical specifications

  • Integrated sampling pump.
  • Flow rate: 1 L / minute
  • Oled screen.
  • Response time: depending on the length of the line, generally under 2 min
  • Power supply: internal rechargeable battery under 230 V – 50/60 Hz.
  • Weight: 4 kg.
  • Dimensions: 23 cm x 20 cm x 11 cm high
  • Sample connection diameter: 6/8

O2 sensor: Zirconium oxide cell:

  • Measuring range: 0 to 25%
  • Sensor accuracy: 0.05% up to 1.5% and 0.1% on the rest of the scale
  • Sensor resolution: 0.01 % up to 1.5% and 0.1 % on the rest of the scale

CO2 sensor: Infrared adsorption detection (NDIR)

  • Measuring range: 0 to 5% (0-10%, 0-30% and 0-100% optional)
  • Sensor accuracy: 0.05% up to 1.5% and 0.1% on the rest of the scale
  • Sensor resolution: 0.01 % up to 1.5% and 0.1 % on the rest of the scale

C2H4 analysers

Technology

The EASI1-N analyser sensor uses a unique, patented nanoporous electrocatalytic sensing element, which is distinct from standard electrochemical sensors.

The main advantages are:

  • Precise, real-time measurement
  • Continuous sampling
  • Sensor consisting of a nanoporous nafion membrane
  • Sensitivity: < 10 ppb

Applications

  • Monitoring and managing FN and CA chambers: a marketing decision tool
  • Monitoring refrigerated containers
  • Checking the effectiveness of 1-MCP treatment
  • Analysing ethylene emission from fruits
