Product facts and notices

  • User-friendly touch screen interface
  • Compatible with any incubator on the market
  • Diffusion or Aspiration gas sampling modes
  • Pump suction rate 100 ml/min
  • Sampling tube and de-humidification kit included
  • Long term logging
  • Micro USB for data download
  • Calibration:
    a) Removable sensors can be shipped to certified
    laboratories to be calibrated. Calibration
    is stored in sensor on-board memory. Leo
    reads calibration upon sensor installation
    b) In situ sensor calibration via LEO calibration

he CO2 – O2 sensors are always included in LEO and are contained in a removable part. They feature local memory storing the calibration data. LEO reads the calibration data from the sensors module upon powering on.

  • CO2 range: 0-20%
  • CO2 accuracy: ± 1.0% of Full scale + 2% reading (at 6% ±0.32%)
  • CO2 Sensor: Non Dispersive InfraRed (NDIR) dual wave length detector with pressure and temperature compensation
  • O2 range: 0-25%
  • O2 accuracy: ±1.0% of Full Scale (at 6% ±0.25%)
  • O2 Sensor: Fluorescence based optical sensor

LEO comes with built-in standard intuitive calibration routines for CO2 – O2 sensors. Calibration requires a reference calibration gas or another reliable measuring device.​

When needed the sensors module can be extracted from LEO and sent out for calibration to any accredited calibration laboratory.
