EL3020-Z023 series gas analyzer


EL3020-Z023 Measurement Principle:

  • Electrochemical Oxygen Sensor

Sample Component and Measurement Range:

  • Sample Component: Oxygen (O2)
  • Smallest Measurement Range: 0–5 Vol.-% O2
  • Measurement Range: Adjustable from 0–5 Vol.-% O2 to 0–25 Vol.-% O2

EL3020-Z023 Stability:

  • Linearity Deviation: Linear in the range > 1 Vol.-% O2
  • Repeatability: ≤ 0.5% of span
  • Zero Drift: Stable over the long term due to absolute zero point
  • Sensitivity Drift: ≤ 1% of the measurement range per week
  • Output Fluctuation (2 σ): ≤ 0.2% of the measurement range at electronic T90 time (static/dynamic) = 5/0 sec
  • Detection Limit (4 σ): ≤ 0.4% of the measurement range at electronic T90 time (static/dynamic) = 5/0 sec

EL3020-Z023 Influence Effects:

  • Flow Effect: ≤ 2% of the measurement range in the 20–100 l/h range
  • Temperature Effect: ≤ 0.2 Vol.-% O2 per 10 °C in the ambient temperature range of +5 to +40 °C
  • Air Pressure Effect:
    • At zero-point: No effect
    • On sensitivity without pressure correction: ≤ 1% of measured value per 1% air pressure change
    • On sensitivity with pressure correction: ≤ 0.2% of sample value per 1% air pressure change
  • Power Supply Effect: ≤ 0.2% of span

Dynamic Response:

  • 90% Response Time (T90): T90 ≤ 30 sec at sample gas flow of 60 l/h and electronic T90 time (static/dynamic) = 5/0 sec


  • Zero-Point Calibration: Oxygen sensor zero is not calibrated due to its fundamental stability.
  • End-Point Calibration: With ambient air at 20.96 Vol.-% O2

Materials in Contact with the Sample Medium:

  • Sensor: Polystyrol-ABS, PTFE, FPM (Fluorocarbon rubber)
  • Housing Body: PVC, FPM (Fluorocarbon rubber) seals
  • Gas Ports: Stainless steel 1.4571

EL3020-Z023 Gas Inlet Conditions:

  • Temperature: Sample gas dew point should be at least 5 °C below the temperature throughout the sample gas path. A sample gas cooler or condensate trap is required otherwise.
  • Moisture Content: H2O dew point ≥ 2 °C. The oxygen sensor should not be used with dry sample gas.
  • Inlet Pressure (pe): Range: 2–500 hPa
  • Outlet Pressure: Atmospheric pressure
  • Flow Rate: 20–100 l/h

EL3020-Z023 Associated Gas:

  • The oxygen sensor should not be used if the associated gas contains the following components: H2S, chlorine or fluorine compounds, heavy metals, aerosols, mercaptane, base components.
