Technical data and functions

Digital carbon dioxide sensor

  • Digital CO2 sensor with integrated signal processor
  • All sensor characteristics and adjustment data are stored in the CO2 sensor itself.
  • The unique automatic calibration procedure (without fresh air intake) automatically compensates any natural ageing effects.
  • The sensor is very well protected against the effects of pollution by means of replaceable PTFE filter caps. Long-term stability is outstanding.
  • Automatic atmospheric pressure compensation is provided for pressure-dependent CO2 concentrations by means of a digital atmospheric pressure sensor integrated in the grip.
  • The relevant ambient parameter, atmospheric pressure, is measured using the same sensor.
  • Long-term measuring operations can be performed with an ALMEMO® data logger in sleep mode; this applies only to current device types with sleep delay (180 seconds).
  • 2 primary measuring channels (real measurable variables) CO2 concentration and atmospheric pressure
  • Freely selectable measurable variables Two measuring channels are programmed (at our factory).
    CO2 concentration, average value (ppm), Atmospheric pressure (mbar, AP, p).
    Alternatively a further variable can be selected.
    CO2 concentration, current value (ppm).



Carbon Dioxide Probe

  • Since the gas is supplied by means of free convection,
    this is especially suitable for climatology measurements.
  • Various measuring ranges up to 25%.
